Timer Mode Register A (TMA)
TMA is an 8-bit read/write register for selecting the prescaler, input clock, and output clock.
Upon reset, TMA is initialized to H'10.
Bits 7 to 5 Clock Output Select (TMA7 to TMA5): Bits 7 to 5 choose which of eight clock
signals is output at the TMOW pin. The system clock divided by 32, 16, 8, or 4 can be output in
active mode and sleep mode. A 32.768 kHz signal divided by 32, 16, 8, or 4 can be output in
active mode, sleep mode, and subactive mode.
