Table 50. Port A Peripheral Data Mode Read Timing
Table 51. Port A Peripheral Data Mode Write Timing
Note: 1. RD has the same timing as DS, LDS, UDS, and PSEN (in 8031 combined mode).
2. WR has the same timing as the E, LDS, UDS, WRL, and 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.
