Operation mode of channel n
110B: Capture & one-count
Setting of operation when
counting is started
0: Does not generate
INTTMmn when counting is
started.
Selection of TImn 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 TImn pin input valid edge.
Setting of MASTERmn bit (channels 2, 4, 6)
0: Independent channel operation
Setting of SPLITmn bit (channels 1, 3)
0: 16-bit timer mode
Count clock selection
0: Selects operation clock (f
MCK
).
Operation clock (f
MCK
) selection
00B: Selects CKm0 as operation clock of channel n.
10B: Selects CKm1 as operation clock of channel n.
01B: Selects CKm2 as operation clock of channels 1, 3 (This can only be selected channels 1 and 3).
11B: Selects CKm3 as operation clock of channels 1, 3 (This can only be selected channels 1 and 3).
Note 1. TMRm2, TMRm4, TMRm6: MASTERmn bit
TMRm1, TMRm3: SPLITmn bit
TMRm0, TMRm5, TMRm7: Fixed to 0
Remark m: Unit number (m = 0), n: Channel number (n = 0 to 7)
