Operation mode of channel n
100B: One-count mode
Start trigger during operation
0: Trigger input is invalid.
Selection of TI0n pin input edge
00B: Detects falling edge.
01B: Detects rising edge.
10B: Detects both edges.
11B: Setting prohibited
Start trigger selection
001B: Selects the TI0n pin input valid edge.
Note2
Setting of MASTER0n bit (Channel 2)
1: Master channel.
Count clock selection
0: Selects operation clock (f
MCK).
Operation clock (f
MCK) selection
0: Selects CK00 as operation clock of channels n.
1: Selects CK01 as operation clock of channels n.
(b) Timer output register 0 (TO0)
Bit n
TO0
TO0n
0
0: Outputs 0 from TO0n.
(c) Timer output enable register 0 (TOE0)
Bit n
TOE0
TOE0n
0
0: Stops the TO0n output operation by counting operation.
(d) Timer output level register 0 (TOL0)
Bit n
TOL0
TOL0n
0
0: Setting is invalid because master channel output mode is set (TOM0n = 0).
Notes 1. TMR02: MASTER02 bit
TMR00: 0 fixed
2. A software operation (TS0n = 1) can be used as a start trigger, instead of using the TI0n pin input.
Remark n: Master channel number (n = 0, 2)
