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.
