However, only the following SFRs are connected with the 16-bit bus:
Interrupts: Each interrupt control register
Timer RC: Registers TRC, TRCGRA, TRCGRB, TRCGRC, and TRCGRD
SSU: Registers SSTDR, SSTDRH, SSRDR, and SSRDRH
UART2: Registers U2MR, U2BRG, U2TB, U2C0, U2C1, U2RB, U2SMR5, U2SMR4, U2SMR3, U2SMR2,
A/D converter: Registers AD0, AD1, AD2, AD3, AD4, AD5, AD6, AD7, ADMOD, ADINSEL, ADCON0,
D/A converter: Registers DA0 and DA1
Address match interrupt: Registers RMAD0, AIER0, RMAD1, and AIER1
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 8.2 Access Units and Bus Operations, and 16-bit data is accessed at a time.
