Function
BC Time Tag Action Bits 1-0.
After performing the action below, these host-written bits self reset to
00:
If BCTT32 register bit 3 equals 0, the BC is using 16-bit time tag. The
BC Time Tag Counter uses a single register address, 0x0043. The
BCMT Time Tag Utility Register used for these operations is register
address 0x003D.
If BCTT32 register bit 3 equals 1 the BC is using 32-bit time tagging,
so the BC Time Tag Counter requires two 16-bit register addresses.
The High and Low BC time tag counter words are found at 0x0044 and
0x0043. The pair of BCMT Time Tag Utility Registers used for timer
operations is located at register addresses 0x003E (High word) and
0x003D (Low word).
RT2 Time Tag Action Bits 1-0.
After performing the RT2 time tag counter action below, these host-
written bits self reset to 00:
