However, only following SFRs are connected with the 16-bit bus:
Timer RC: registers TRC, TRCGRA, TRCGRB, TRCGRC, and TRCGRD
Timer RD: registers TRDi (i = 0,1), TRDGRAi, TRDGRBi, TRDGRCi, and TRDGRDi
Therefore, they are accessed once in 16-bit units. The bus operation is the same as “Area: SFR, data flash, even address
byte access” in Table 9.3 Access Units and Bus Operations, and 16-bit data is accessed at a time.
