The parity control register (PCR) is a 16-bit read/write register that selects the parity polarity and
space to be parity checked. PCR is initialized to H'0000 by a power-on reset, but is not initialized
by a manual reset or in standby mode.
Bit 15—Parity Error Flag (PEF): When a parity check is carried out, PEF indicates whether a
parity error has occurred. 0 indicates that no parity error has occurred; 1 indicates that a parity
error has occurred.
