Section 24 List of Registers

This section gives information on the on-chip I/O registers and is configured as described below.

1. Register Addresses (by functional module, in order of the corresponding section numbers)
• Descriptions by functional module, in order of the corresponding section numbers

Entries that consist of - lines are for separation of the functional modules.

• Access to reserved addresses which are not described in this list is prohibited.
• When registers consist of 16 or 32 bits, the addresses of the MSBs are given.

2. Register Bits
• Bit configurations of the registers are described in the same order as the Register Addresses

(by functional module, in order of the corresponding section numbers).

• Reserved bits are indicated by—in the bit name.
• No entry in the bit-name column indicates that the whole register is allocated as a counter or

for holding data.

• When registers consist of 16 or 32 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 (by functional

module, in order of the corresponding section numbers).

• For the initial state of each bit, refer to the description of the register in the corresponding

section.

• The register states described are for the basic operating modes. If there is a specific reset for an

on-chip module, refer to the section on that on-chip module.
