Table 7-2 SETTING SECONDARY INTERFACE DETECTED PARITY ERROR BIT
Table 7-3 SETTING PRIMARY INTERFACE DATA PARITY ERROR DETECTED BIT
X = don’t care
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 PI7C7300A detects a
parity error on the secondary interface.
X = don’t care
Table 7-3 shows setting data parity detected bit in the primary interface’s status register.
This bit is set under the following conditions:

PI7C7300A 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.
