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.
• When the address is 16-bit wide, the address of the upper byte is given in the list.
• 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.
• Reserved bits are indicated by in the bit name column.
• Bit number in the bit-name column indicates that the whole register is allocated as a counter or
for holding data.
• When registers consist of 16 bits, bits are described from the MSB side.
3. Register states in each operating mode
• Register states are described in the same order as the register addresses.
• 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.
