Table 62. Port A Peripheral Data Mode READ Timing (3V devices)
Figure 48. Peripheral I/O WRITE Timing
Table 63. Port A Peripheral Data Mode WRITE Timing (5V devices)
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.
