(3) System status register (SYS)
Status flags that indicate the operation status of the overall system are allocated to this register.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
The PRERR flag operates under the following conditions.
(a) Set condition (PRERR flag = 1)
(b) Clear condition (PRERR flag = 0)
(i) When data is written to a special register without writing anything to the PRCMD register (when <4> is
(ii) When data is written to an on-chip peripheral I/O register other than a special register (including execution
Remark
(i) When 0 is written to the PRERR flag
(ii) When the system is reset
Cautions 1. If 0 is written to the PRERR bit of the SYS register, which is not a special register,

of a bit manipulation instruction) after writing data to the PRCMD register (if <4> in 3.4.8 (1) Setting data

2. If data is written to the PRCMD register, which is not a special register, immediately after a
Even if an on-chip peripheral I/O register is read (except by a bit manipulation instruction) between
an operation to write the PRCMD register and an operation to write a special register, the PRERR
flag is not set, and the set data can be written to the special register.
immediately after a write access to the PRCMD register, the PRERR bit is cleared to 0 (the
write access takes precedence).
write access to the PRCMD register, the PRERR bit is set to 1.
