ture mode
Setting of operation when counting is started
0: Does not generate INTTM0n when
counting is started.
1: Generates INTTM0n when counting is
started.
Selection of TI0n pin input edge
00B: Detects falling edge.
01B: Detects rising edge.
10B: Detects both edges.
11B: Setting prohibited
Capture trigger selection
001B: Selects the TI0n pin input valid edge.
Note2
Setting of MASTER0n bit (Channel 2)
0: Independent channel operation
Setting of SPLIT0n bit (Channel 1, 3)
0: 16-bit timer
Count clock selection
0: Selects operation clock (f
MCK).
Operation clock (f
MCK) selection
0: Selects CK00 as operation clock of channel n.
1: Selects CK01 as operation clock of channel n.
(b) Timer output register 0 (TO0)
Bit n

0
0: Outputs 0 from TO0n.
(c) Timer output enable register 0 (TOE0)
Bit n
TOE0
TOE0n
0
0: Stops TO0n output operation by counting operation.
Notes 1. TMR02: MASTER0n bit
TMR01, TMR03: SPLIT0n bit
TMR00: 0 fixed
2. A software operation (TS0n = 1) can be used as a capture trigger, instead of using the TI0n pin input.
Remark n: Channel number
n = 0, 1 (for 10-pin products); n = 0 to 3 (for 16-pin products)
