Section 8 Bus State Controller (BSC)
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 high-level output from the DPH and DPL pins when data is output,
regardless of the parity.
Bit 14: PFRC
0
1
Description
Parity output not forced
High output forced
(Initial value)
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.
Bit 13: PEO
0
1
Description
Even parity
Odd parity
(Initial value)
Bits 12 and 11—Parity Check Enable Bits 1 and 0 (PCHK1 and PCHK0): These bits
determine whether or not parity is checked and generated, and select the check and generation
spaces.
Bit 12:
PCHK1
0
1
Bit 11:
PCHK0
0
1
0
1
Description
Parity not checked and not generated
Parity checked and generated only in DRAM area
Parity checked and generated in DRAM area and area 2
Reserved
(Initial value)
Bits 10–0—Reserved: These bits are always read as 0. The write value should always be 0.
