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
• 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
• Each line covers eight bits, so 16-bit registers are shown as 2 lines.
3. Register States in Each Operating Mode
• Register states are described in the same order as the Register Addresses (Address Order)
• The register states described here are for the basic operating modes. If there is a specific reset
