(2) Command register
PRCMD 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. This register can be
used as PRCMD or PRCMD2 via a special register setting. The first write access to a special register is valid
after data has been written in advance to the command 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.
(a) Command register (PRCMD)
(b) Command register 2 (PRCMD2)
The PRCMD register is write-only, in 8-bit units (undefined data is read when this register is read).
Reset makes this register undefined.
Caution After writing to the PRCMD register, writing to special registers PSC, CKC, PCC, CLM,
The PRCMD2 register is write-only, in 8-bit units (undefined data is read when this register is read).
Reset makes this register undefined.
Caution After writing to the PRCMD2 register, writing to special registers LVIM and RAMS is
PRCMD2
