Table 7–3 shows setting data parity detected bit in the primary interface’s status register. This bit is set under the following
conditions:
• PI7C7100 must be a master on the primary bus.
• The parity error response bit in the command register, corresponding to the primary interface, must be set.
• The P_PERR# signal is detected asserted or a parity error is detected on the primary bus.

Table 7–2. Setting Secondary Interface Detected Parity Error Bit
Table 7–2 shows setting the detected parity error bit in the secondary status register, corresponding to the secondary
interface. This bit is set when PI7C7100 detects a parity error on the secondary interface.
