Figure 12.19 Timer Y operation example in programmable waveform generation mode
Programmable waveform generation output switching function
When the Timer Y programmable waveform generation output switching bit (bit 1 at address 008A16)
is set to 0, the output from TYOUT is inverted synchronously when the Timer Y secondary underflows.
And when set to 1, the Port P32 register value is output from TYOUT synchronously when the Timer Y
secondary underflows.
