Function
Monitor Time Tag Message Bit Select.
This 2-bit field selects the bit within the MIL-STD-1553 message where
time stamp occurs. Time stamp occurs at mid-bit transition:
For options 00 and 10, the “Last Bit” precedes the word’s parity bit. For
option 01, the “First Bit” occurs 0.5µs after command sync. While “First
Word” generally denotes a command word, message recording can
begin with a data word when register bit 5 equals 1.
Bit 7 is not used by the bus monitor operating in SMT mode.
Initialize this bit to logic 0.
