Perform the following for the timer mode (input capture and output compare functions).
When using the TRDGRCi (i = 0 or 1) register as the buffer register of the TRDGRAi register
When using the TRDGRDi register as the buffer register of the TRDGRBi register
Bits IMFC and IMFD in the TRDSRi register are set to 1 at the input edge of the TRDIOCi pin when also using
registers TRDGRCi and TRDGRDi as the buffer register in the input capture function.
When using the TRDGRCi and TRDGRDi registers for the buffer register in output compare function, reset
synchronous PWM mode, complementary PWM mode and PWM3 mode, the IMFC and IMFD bits in the
TRDSRi register are set to 1 by the compare match with the TRDi register.
• Set the IOC3 bit in the TRDIORCi register to 1 (general register or buffer register).
• Set the IOC2 bit in the TRDIORCi register to the same as the IOA2 bit in the TRDIORAi register.
• Set the IOD3 bit in the TRDIORDi register to 1 (general register or buffer register).
• Set the IOD2 bit in the TRDIORCi register to the same value as the IOB2 bit in the TRDIORAi register.
i = 0 or 1
The above applies to the following conditions:
• BFCi bit in the TRDMR register is set to 1. (The TRDGRCi register is used as the buffer register of
• IOA2 to IOA0 bits in the TRDIORAi register are set to 001b (“L” output by the compare match).
the TRDGRAi register.)
