IUSER[2:0]
IPAGE[1:0]
TX_LINK[1:0]
TX_MSG_LVL_VALID
Values greater than 1000 will not occur. The number of free messages available in the FIFO is
given by 8 – TX_MSG_LVL.
These bits are a reflection of the USER[2:0] bits output in the header of the in-band link on
the Transmit Protection Serial Link. IUSER[2] is sourced from the IUSER2 input to the SBS.
IUSER[1:0] is sourced from the TXWUSER[1:0] bits of register 008H.
These bits are a reflection of the PAGE[1:0] bits output in the header of the in-band link on
the Transmit Protection Serial Link. PAGE[1] reflects the current memory page used by the
IMSU. PAGE[0] reflects the current memory page used by the OMSU.
These bits reflect the last written value of the TX_LINK[1:0] field of the PILC Transmit
Control Register. The upper byte of this register therefore reflects all of the configurable bits
of the message Header1 byte.
This bit indicates that the value of TX_MSG_LVL is valid. When read with a logic zero this
register should be re-read until TX_MSG_LVL_VALID is a logic one. This bit will be clear
for only approximately 0.3% of the time.
