Bit 15 (parity error flag (PEF)): When a parity check is done, PEF indicates whether a parity
error has occurred. 0 indicates that no parity error has occurred; 1 indicates that a parity error
has occurred.
Bit 14 (parity output force (PFRC)): PFRC selects whether to produce a forced parity output
for testing the parity error check function. When cleared to 0, there is no forced output; when
set to 1, it produces a forced output of high level from the DPH and DPL pins when data is
output, regardless of the parity.
Bit 13 (parity polarity (PEO)): PEO selects even or odd parity. When cleared to 0, parity is
even; when set to 1, parity is odd.
Bits 12 and 11 (parity check enable bits 1, 0 (PCHK1 and PCHK0)): These bits determine
whether or not a parity is checked and generated, and select the check and generation spaces.
