Section 25 List Of Registers - Renesas H8S Series Hardware Manual

The list of registers gives information on the on-chip I/O 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.
• H8S/2140B Group compatible register addresses or extended register addresses are selected
depending on the RELOCATE bit in system control register 3 (SYSCR3).
When the extended register addresses are selected, the some register addresses of ICC_1,
TMR_Y, PWMX_0 and PORT are changed. Therefore, the selection with other module
registers that share the same addresses with these registers is not necessary.
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
counter or for holding data.
• 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
for an on-chip peripheral module, see the section on that on-chip peripheral module.
4. Register selection conditions
• Register selection conditions are described in the same order as the register addresses.
• Register selection conditions with the RELOCATE bit in the system control register 3
(SYSCR3) cleared to 0 are indicated. For details, see section 3.2.2, System Control Register
(SYSCR), section 3.2.3, Serial Timer Control Register (STCR), section 23.1.3, Module Stop
Control Register H, L, A (MSTPCRH, MSTPCRL, MSTPCRA), or register descriptions for
each module.
