Port A Peripheral Data Mode Read Timing (3.0 V ± 10%)

NOTES: 1. Any input used to select an internal ZPSD5XX function.

2. WR timing has the same timing as E, DS, LDS, UDS, WRL, WRH signals.

3. Any input used to select Port A Data Peripheral Mode.

4. Data is already stable on Port A.

5. Data stable on ADIO pins to data on Port A.

*NOTE: If ZPLD_TURBO is off and the ZPLD is operating above 15 MHz, there is no need to add 20 ns to the timing parameters.
