This table lists the I/O registers in both 5-V and 3-V package specifications. The I/O registers of each product correspond to the functions listed in Table 1.2. For details,
see Table 1.2, Comparison of Functions of Different RX634 Group Products.
The CEC, RCR0, and RCR1 are not available in 5-V packages.
Odd addresses cannot be accessed in 16-bit units. When accessing a register in 16-bit units, access the address of the TMR0 or TMR2 register.
Odd addresses cannot be accessed in 16-bit units. When accessing a register in 16-bit units, access the address of the TMOCNTL register.
