About access size and bit position

When access size changes, bit position changes.

• In the case that address offset value is +0 (Example: CCRH0 register)

• In the case that address offset value is +1 (Example: CCRL0 register)

• In the case that address offset value is +2 (Example: UDCR1 register)

• In the case that address offset value is +3 (Example: UDCR 1 register)
