Function
MT Time Tag Action Bits 1-0.
After performing the action below, these host-written bits self reset to
00:
If the MT is using 16-bit time tag, the MT Time Tag Counter uses a
single register address, 0x003A. The BCMT Time Tag Utility Register
used for the load and capture operations is register address 0x003D.
If the MT is using 48-bit time tag, the MT Time Tag Counter uses three
register addresses. The High-Mid-Low words are found at 0x003C,
0x003B and 0x003A. The triplet of BCMT Time Tag Utility Registers
used for the load and capture operations is located at register
addresses 0x003F (High), 0x003E (Mid) and 0x003D (Low).
Function
Bits 1-0 in the MT Configuration Register, 0x0029 select IRIG-106
monitor, IMT (always 48-bit time tag counting), or simple monitor, SMT,
(choice of 16-bit or 48-bit time tag counting):
When the MT is operating in Simple mode with 48-bit time tag, the
recorded Command Stack entry for each 1553 message has eight 16-
bit words. When operating with 16-bit time tag, the recorded Command
Stack entry for each 1553 message has four 16-bit words.
