SYS
Word Bit Description
SYS15 Status of On-board Command Blocks
Module latches bits individually when it successfully decodes the referenced command block and places new data into
operational memory. The module does not latch any bit associated with an unrecognizable command block.
Module unlatches all bits in this word:
S on power start-up, or
S when it receives a new MCC for decode
This bit
latched ON: when this on-board block is valid:
B00 MCC
B01 JGC
B02-06 RFU
B07 INC
B08 IPC The module also unlatches this bit when it successfully decodes a new INC.
B09 PKC
B10 HDC
B11 HPC The module also unlatches this bit when it successfully decodes a new PKC or HDC.
B12 PRC
B13 PLC
B14 PPC The module also unlatches this bit when it successfully decodes a new PLC.
B15 PSC
SYS16 Status of On-board Command Block
The module latches bits individually when it successfully decodes the referenced command block and places new data
into operational memory. The module does not latch any bit associated with an unrecognizable command block.
The module unlatches all bits in this word on power start-up or when it receives a new MCC for decoding.
This bit
latched ON: when this on-board block is valid:
B00-07 RFU
B08 DYC
B09 RLC
B10 RFU
B11 PTC
B12-B15 RFU
SYS17 Status of Last Successful Decode
The module latches one of the bits in SYS17 and SYS18 (while unlatching all others) when it successfully decodes the
referenced command block and places the new data into operational memory. The module does not latch any bit asso-
ciated with an unrecognizable command block. Set no more than one bit at a time in SYS17 and SYS18.
This bit
latched ON: when last successful decode was:
B00 MCC
B01 JCC
B02-06 RFU
B07 INC
B08 IPC
B09 PKC
B10 HDC
B11 HPC
B12 PRC
B13 PLC
B14 PPC
B15 PSC
