Section 24 List of Registers
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.
