Operation mode of channel n 
100B: One-count mode 
Start trigger during operation
0: Trigger input is invalid.
1: Trigger input is valid. 
Selection of TImn pin input edge 
00B: Detects falling edge. 
01B: Detects rising edge. 
10B: Detects both edges. 
11B: Setting prohibited 
Start trigger selection 
001B: Selects the TImn pin input valid edge. 
Setting of MASTERmn bit (channels 2, 4, 6) 
0: Independent channel operation function. 
Setting of SPLITmn bit (channels 1, 3) 
1: 8-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). 
(b)  Timer output register m (TOm) 
  Bit n
