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.
