W Puts the 71M6533/71M6534 into SLEEP mode. This bit is ignored if system power is
present. The 71M6533 and 71M6534 will wake when the autowake timer times out,
when the push button is pushed, when system power returns or when RESET goes
high.
0 R/W When set to 1, selects differential mode for the corresponding current input (IA, IB, IC,
0
or ID). When 0, the input remains single-ended.
0
0
0 R/W Primary multiplexer frame analog input selection. These bits map the selected input,
1
0-9 to the multiplexer state. The ADC output is always written to the memory location
…
corresponding to the input, regardless of which multiplexer state an input is mapped to
8
(see Section 1.2 Analog Front End (AFE)).
9
10 R/W Alternate multiplexer frame analog input selection. Maps the selected input, 0-11, to
the multiplexer state.
1
The additional inputs, 10 and 11 in the alternate frame are:
10 = TEMP
11
11 = VBAT

–
R SPI Address. 16-bit address from the bus master.
R
–
R SPI command. 8-bit command from the bus master.
0 R/W SPI port enable. Enables the SPI interface on pins SEG3 through SEG5.
R/W SPI interrupt flag. The flag is set by the hardware and is cleared by the firmware writ-
ing a 0. Firmware using this interrupt should clear the spurious interrupt indication dur-
ing initialization.
–
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.
0 R/W The number of pre-summer outputs summed in the final summer.
– R/W Selects one of 32 signals for TMUXOUT. For details, see Section 1.4.13 Test Ports
(TMUXOUT Pin).
