The above applies under the following conditions:
• The BFC bit in the TRCMR register is set to 1 (the TRCGRC register functions as the buffer register for the TRCGRA register).
• Bits IOA2 to IOA0 in the TRCIOR0 register are set to 100b (input capture at the rising edge).
Bits BFC and BFD in the TRCMR register are used to select the TRCGRC or TRCGRD register as the buffer
register for the TRCGRA or TRCGRB register.
• Buffer register for TRCGRA register: TRCGRC register
• Buffer register for TRCGRB register: TRCGRD register
Buffer operation differs depending on the mode.
Table 19.6 lists the Buffer Operation in Each Mode, Figure 19.3 shows the Buffer Operation for Input Capture
Function, and Figure 19.4 shows the Buffer Operation for Output Compare Function.
