Operation mode of channel q
110B: Capture & one-count
Setting of operation when counting is started
0: Does not generate INTTMpq when
counting is started.
Selection of TIpq pin input edge
10B: Both edges (to measure low-level width)
11B: Both edges (to measure high-level width)
Start trigger selection
010B: Selects the TIpq pin input valid edge.
Slave/master selection
0: Cleared to 0 when independent function is selected.
Count clock selection
0: Selects operation clock.
Operation clock selection
0: Selects CKp0 as operation clock of channel q.
1: Selects CKp1 as operation clock of channel q.
(b) Timer output register p (TOp)

0
0: Outputs 0 from TOpq.
(c) Timer output enable register p (TOEp)

0
0: Stops the TOpq output operation by counting operation.
(d) Timer output level register p (TOLp)
Bit q

0
0: Cleared to 0 when TOMpq = 0 (toggle mode).
(e) Timer output mode register p (TOMp)

TOMpq
0
0: Sets toggle mode.
Remark
pq: Unit number + Channel number (only for channels provided with timer I/O pins)
78K0R/LF3: p = 0, pq = 00 to 04, 07
78K0R/LG3: p = 0, pq = 00 to 07
78K0R/LH3: p = 0, 1, pq = 00 to 07, 10 to 13
