 PWM output: The operation is basically the same as that of timer-C’s PWM output.
• Input capture timer operation: The input capture timer counts the clock cycles between trigger edges
input to pin EVND.
Either falling or rising edge, or both falling and rising edges of input signals can be selected as the
trigger input edge by detection edge select register 2 (ESR2: $027).
When a trigger edge is input to EVND, the count of timer D is written to timer read register D (TRDL:
$011, TRDU: $012), and the timer D interrupt request flag (IFTD: $003, bit 0) and the input capture
status flag (ICSF: $021, bit 0) are set. Timer D is reset to $00, and then incremented again. While
ICSF is set, if a trigger input edge is applied to timer D, or if timer D generates an overflow, the input
capture error flag (ICEF: $021, bit 1) is set. ICSF and ICEF are reset to 0 by MCU reset or by writing
0.
By selecting the input capture operation, pin R3₂/TOD is set to R3₂ and timer D is reset to $00.
