The list of registers gives information on the on-chip register addresses, how the register bits are
configured, the register states in each operating mode, the register selection condition, and the
register address of each module. The information is given as shown below.
1. Register addresses (address order)
• Registers are listed from the lower allocation addresses.
• For the addresses of 16 bits, the MSB is described.
• 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, and 16-bit register is shown as 2 lines, respectively.
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
4. Register selection conditions
• Register selection conditions are described in the same order as the register addresses.
• Register selection conditions are described in section 3.2.2, System Control Register (SYSCR),
5. Register addresses (classification by type of module)
• The register addresses are described by modules.
• The register addresses are described in channel order when the module has multiple channels.
