S can be selected, or timer B can be used as an external event counter

• By setting timer mode register B2 (TMB2: $026), detection edge type of EVNB can be selected.

• By setting timer write register BL, U (TWBL, U: $00A, $00B), timer counter B (TCB) can be written

to during reload timer operation

• By setting timer read register BL, U (TRBL, U: $00A, $00B), the contents of timer counter B can be
