3.2.19 CARRY Register: Carry Selection for External Output
NOTE:
SMSC TMC2072
OFSMOD (CARRY register: bit 15)
0: Automatic offset (default)
1: Manual offset
NSTOFS4-0 (CARRY register: bits 12 to 8)
These bit selects an offset from 0 to 31. The offset is “NST resolution * NSTOFS4-0”.
NSTC3-0 (bits 7 to 4)
These bits specify the generation timing of external pulse output, nNSTCOUT, by means of the digit
position of NST.
Refer to section 2.11 - Network Standard Time (NST) for the NST resolution.
WARTC3-0 (bits 3 to 0)
These bits specify the warning monitoring time at remote buffer receive by means of the digit position of
timer (WT). Refer to section 2.9.4 - Warning Timer (WT) at Remote Buffer Receive for details of WT.
Do not set OFSMOD bit = 1, when NSTPRE2 pin = Low
