This LSI allows interconnection between a 16-bit free-running timer (FRT) and three 8-bit timer
channels (TMR_1, TMR_X, and TMR_Y). This capability can be used to implement complex
functions such as PWM decoding and clamp waveform output.

Figure 13.1 shows a block diagram of the timer connection facility.
TIMC0N01_010020020700
Five input pins and four output pins, all of which can be designated for phase inversion.
Positive logic is assumed for all signals used within the timer connection facility.
An edge-detection circuit is connected to the input pins, simplifying signal input detection.
TMR_X can be used for PWM input signal decoding.
TMR_X can be used for clamp waveform generation.
An external clock signal divided by TMR_1 can be used as the FRT capture input signal.
An internal synchronization signal can be generated using the FRT and TMR_Y.
A signal generated/modified using an input signal and timer connection can be selected and
output.
