R
SPI Address. 16-bit address from the bus master.

R SPI command. 8-bit command from the bus master.
0
0 R/W SPI port enable. Enables the SPI interface on pins SEG3 through SEG6.
SPI interrupt flag. The flag is set by the hardware and is cleared by the firmware
R/W writing a 0. Firmware using this interrupt should clear the spurious interrupt indication
during initialization.
The remaining count, in terms of 1/256 RTC cycles, to the next one second boundary.

R 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
0 R/W The number of pre-summer outputs summed in the final summer.

Selects one of 32 signals for TMUXOUT. For details, see Section 1.5.13 Test Ports
(TMUXOUT Pin).
Contains TRIMT[7:0], TRIMBGA,TRIMBGB or TRIMM[2:0] depending on the value
0
0 R/W written to TRIMSEL[3:0]. If TRIMBGB = 0, the device is a 71M6533/71M6534, else it is
a 71M6533H/71M6534H.
Selects the temperature trim fuse to be read with the TRIM register:
