This LSI incorporates the timer connection with two channels. The timer connection allows
interconnection by using the combination of input pins and I/O for a 16-bit free-running timer
(FRT) and 8-bit timer (TMR1, TMRX, and TMRY). This capability can be used to implement
complex functions such as PWM decoding and clamp waveform output.
13.1
• Eight input pins and four output pins, all of which can be designated for phase.
• An edge-detection circuit is connected to the input pins, simplifying signal input detection.
• TMRX can be used for PWM input signal decoding.
• TMRX can be used for clamp waveform generation.
• An external clock signal divided by TMR1 can be used as the FRT capture input signal.
• An internal synchronization signal can be generated using the FRT and TMRY.
• A signal generated/modified using an input signal and timer connection can be selected and
This LSI incorporates the timer connection with two channels and some output pins are shared.
Figure 13.1 shows a schematic diagram of the timer connection.
