ARMSELx

00 ARMINT select for safing record x - correlates ARMINT 1 and ARMINT2 (as

determined by ARM1x and ARM2x bits) to ARMP and ARMN

Updated by SSM_RESET or SPI write while in DIAG state

00 ARMP OR ARMN

01 ARMP

10 ARMN

11 ARMP OR ARMN

SPIFLDSELx

0 SPI field select for safing record x - determines which 16-bit field in long SPI

messages (>31 bit) to use for response on MISO of SPI monitor. In case of

messages less than 32 bits this bit is don't care.
