FDS_6533_6534_004 71M6533/G/H and 71M6534/H Data Sheet Rev 2 93 SLOT0_ALTSEL [3:0] SLOT1_ALTSEL [3:0] SLOT2_ALTSEL [3:0] … SLOT8_ALTSEL [3:0] SLOT9_ALTSEL [3:0] 2096[3:0] 2096[7:4] 2097[3:0] … 209A[3:0] 209A[7:4] 10 1 11 … 8 9 10 1 11 … 8 9 R/W Alternate multiplexer frame analog input selection. Maps the selected input, 0-11, to the multiplexer state. The additional inputs, 10 and 11 in the alternate frame are: 10 = TEMP 11 = VBAT SP_ADDR[15:8] SP_ADDR[7:0] 2072[7:0] 2073[7:0] – – R R SPI Address. 16-bit address from the bus master. SP_CMD 2071 – – R SPI command. 8-bit command from the bus master. SPE 2070[7] 0 0 R/W SPI port enable. Enables the SPI interface on pins SEG3 through SEG6. SPI_FLAG 20B1[4] R/W SPI interrupt flag. The flag is set by the hardware and is cleared by the firmware writing a 0. Firmware using this interrupt should clear the spurious interrupt indication during initialization. SUBSEC[7:0] 2014[7:0] – – R The remaining count, in terms of 1/256 RTC cycles, to the next one second boundary. SUBSEC may be read by the MPU after the one second interrupt and before reaching the next one second boundary. Setting RST_SUBSEC will clear SUBSEC. SUM_CYCLES[5:0] 2001[5:0] 0 0 R/W The number of pre-summer outputs summed in the final summer. TMUX[4:0] 20AA[4:0] 2 – R/W Selects one of 32 signals for TMUXOUT. For details, see Section 1.5.13 Test Ports (TMUXOUT Pin). TRIM[7:0] 20FF 0 0 R/W Contains TRIMT[7:0], TRIMBGA,TRIMBGB or TRIMM[2:0] depending on the value written to TRIMSEL[3:0]. If TRIMBGB = 0, the device is a 71M6533/71M6534, else it is a 71M6533H/71M6534H. TRIMSEL[3:0] 20FD[3:0] 0 0 R/W Selects the temperature trim fuse to be read with the TRIM register: TRIMSEL[3:0] Trim Fuse Purpose 1 TRIMT[7:0] Trim for the magnitude of VREF 4 TRIMM[2:0] Trim values related to temperature compensation 5 TRIMBGA 6 TRIMBGB UMUX_E† 200F[7] 0 0 R/W Enables the optical UART multiplexer, selects the alternate function (MTX, MRX) for DIO18, DIO22. UMUX_SEL† S00F[6] 0 0 R/W When UMUX_E = 1, selects between OPT_TX, OPT_RX and MTX, MRX as the optical UART I/O pins. 0 = OPT_TX, OPT_RX, 1 = MTX, MRX |
