C
Interrupt Mask Interrupt Mask
0000 hex: Enable (unmask) the interrupt (direct mode).
0001 hex: Disable (mask) the interrupt (direct mode).
0000 hex: Up-differentiation (Detect rising edge.)
0001 hex: Down-differentiation (Detect falling edge.)
Operand Contents
NScheduled Interrupt No.
4 or 14: Scheduled interrupt 0 (interrupt task 1)
C
Scheduled interrupt time units Scheduled interrupt set time
Any time unit setting 0 decimal (0000 hex):
Disable interrupt. (Stop internal timer.)
0.1 ms 10 to 9,999 decimal (000A to 270F hex):
Enable interrupt. (Reset internal timer value, and then start timer with interrupt interval between
1.0 and 999.9 ms.)
NoteSettings 0001 to 000A cannot be used. An error will occur if one of these settings is used.
N: Interrupt identifier
