54 / 67 page MAX11359A 16-Bit Data-Acquisition System with ADC, DAC, UPIOs, RTC, Voltage Monitors, and Temp Sensor 54 Maxim Integrated MSB MLDVD MLCPD MADO MSDC MCRDY MADD MALD X LSB MUPR4 MUPR3 MUPR2 MUPR1 MUPF4 MUPF3 MUPF2 MUPF1 IMSK Register (Power-On State: 1111 011X 1111 1111) MSB LSB LDOE CPE LSDE CPDE HYSE RSTE X X PS_VMONS Register (Power-On State: 0010 01XX) This register is the power-supply and voltage monitors control register. LDOE: Low-dropout linear-regulator enable bit. Set LDOE = 1 to enable the low-dropout linear regulator to provide the internal source voltage for the charge pump. Set LDOE = 0 to disable the LDO, allowing an external drive to the charge-pump input through REG. The power-on default value is 0. CPE: Charge-pump enable bit. Set CPE = 1 to enable the charge-pump doubler, and set CPE = 0 to disable the charge-pump doubler. The power-on default value is 0. LSDE: DVDD low-supply voltage-detector power- enable bit. Set LSDE = 1 to enable the +1.8V (DVDD) low-supply-voltage detector, and set LSDE = 0 to disable the DVDD low-supply-voltage detector. The power-on default value is 1. CPDE: CPOUT low-supply voltage-detector power- enable bit. Set CPDE = 1 to enable the +2.7V CPOUT low-supply voltage-detector comparator, and set CPDE = 0 to disable the CPOUT low-supply voltage-detector comparator. The power-on default value is 0. HYSE: DVDD low-supply voltage-detector hysteresis- enable bit. Set HYSE = 1 to set the hysteresis for the +1.8V (DVDD) low-supply-voltage detector to +200mV, and set HYSE = 0 to set the hysteresis to +20mV. On initial power-up, the hysteresis is +20mV and can be pro- grammed to 200mV once RESET goes high. Once pro- grammed to +200mV, the DVDD falling threshold is +1.8V nominally and the rising threshold is +2.0V nominally. The The IMSK register determines which bits of the STATUS register generate an interrupt on INT. The bits in this register do not mask output signals routed to UPIO since the output signals are masked by disabling that UPIO function. MLDVD: LDVD status bit mask. Set MLDVD = 0 to enable the LDVD status bit interrupt to INT, and set MLDVD = 1 to mask the LDVD status bit interrupt. The power-on default value is 1. MLCPD: LCP status bit mask. Set MLCPD = 0 to enable the LCP status bit interrupt to INT, and set MLCPD = 1 to mask the LCP status bit interrupt. The power-on default value is 1. MADO: ADO status bit mask. Set MADO = 0 to enable the ADO status bit interrupt to INT, and set MADO = 1 to mask the ADO status bit interrupt. The power-on default value is 1. MSDC: SDC status bit mask. Set MSDC = 0 to enable the SDC status bit interrupt to INT, and set MSDC = 1 to mask the SDC status bit interrupt. The power-on default value is 1. MCRDY: CRD status bit mask. Set MCRDY = 0 to enable the CRDY status bit interrupt to INT, and set MCRDY = 1 to mask the CRDY status bit interrupt. The power-on default value is 0. MADD: ADD status bit mask. Set MADD = 0 to enable the ADD status bit interrupt to INT, and set MADD = 1 to mask the ADD status bit interrupt. The power-on default value is 1. MALD: ALD status bit mask. Set MALD = 0 to enable the ALD status bit interrupt to INT, and set MALD = 1 to mask the ALD status bit interrupt. The power-on default value is 1. MUPR<4:1>: UPR<4:1> status bits mask. Set MUPR_ = 0 to enable the UPR_ status bit interrupt to INT, and set MUPR_ = 1 to mask the UPR_ status bit interrupt. (_ = 1, 2, 3, or 4 and corresponds to the UPIO1, UPIO2, UPIO3, or UPIO4 pins, respectively.) The power-on default value is F hex. MUPF<4:1>: UPF<4:1> status bits mask. Set MUPF_ = 0 to enable the UPF_ status bit interrupt to INT, and set MUPF_ = 1 to mask the UPF_ status bit interrupt. (_ = 1, 2, 3, or 4 and corresponds to the UPIO1, UPIO2, UPIO3, or UPIO4 pins, respectively.) The power-on default value is F hex. |
