The register list gives information on the on-chip I/O register addresses, how the register bits are
configured, and the register states in each operating mode. The information is given as shown
below.
1. Register Addresses (address order)
• Registers are listed from the lower allocation addresses.
• The MSB-side address is indicated for 16-bit addresses.
• Registers are classified by functional modules.
• The access size is indicated.
2. Register Bits
• Bit configurations of the registers are described in the same order as the Register Addresses
(address order) above.
• Reserved bits are indicated by in the bit name column.
• The bit number in the bit-name column indicates that the whole register is allocated as a
counter or for holding data.
• 16-bit or 24-bit registers are indicated from the bit on the MSB side.
3. Register States in Each Operating Mode
• Register states are described in the same order as the Register Addresses (address order)
above.
• The register states described here are for the basic operating modes. If there is a specific reset
for an on-chip peripheral module, refer to the section on that on-chip peripheral module.
23.1
Register Addresses (Address Order)
The data bus width indicates the numbers of bits by which the register is accessed.
The number of access states indicates the number of states based on the specified reference clock.
Note: Access to undefined or reserved addresses is prohibited. Since operation or continued
operation is not guaranteed when these registers are accessed, do not attempt such access.
