Use case range syntax makes the code shorter with better readability when we have a large number of continuous switch cases.
Below are the summary of readable/volatile/precious registers.
The readable registers: 0x01 ~ 0x0D, 0x0F ~ 0x1C The volatile registers: 0x01 ~ 0x05, 0x15 ~ 0x18 The precious registers: 0x15 ~ 0x18
No functional change with this patch.
