(2) Command register (PRCMD)
The PRCMD register is an 8-bit register that protects the registers that may seriously affect the application
system from being written, so that the system does not inadvertently stop due to a program hang-up. The first
write access to a special register is valid after data has been written in advance to the PRCMD register. In this
way, the value of the special register can be rewritten only in a specific sequence, so as to protect the register
from an illegal write access.
The PRCMD register is write-only, in 8-bit units (undefined data is read when this register is read).
