Pulse output port mode
Figure 48 shows the pulse output port mode block diagram.
This mode has an 8-bit pulse output port. The waveform output se-
lect bits (bits 0 to 2) of waveform output mode register (address
1A
put port is divided into 4 bits and 4 bits, or 6 bits and 2 bits with the
pulse output mode select bit (bit 4) of pulse output data register 1
(address 1C

Set timers A1 and A0 to the timer mode because they are used in the
pulse output mode. Additionally, set bit 2 of the corresponding timer
Ai mode register to “1” to use a pulse output port because the pulse
output port are multiplexed with the TAi

Timers A1 and A0 start count when setting the corresponding timer
