Preliminary Specification
This is a preliminary specification and is subject to change.
17. Timer A
Pulse Width Modulation Mode (16-Bit PWM Mode)
If the TAi register is set to 0000h, the counter does not work, the output level on the TAiOUT pin
remains low, and timer Ai interrupt requests are not generated.
Pulse Width Modulation Mode (8-Bit PWM Mode)
This mode operates as 8-bit prescaler (eight low-order bits) and 8-bit pulse width modulator (eight high-
order bits). When the eight high-order bits of the TAi register are set to 00h, the counter does not work,
the output level on the TAiOUT pin remains low, and timer Ai interrupt requests are not generated.
