1. PTA0 must have a pullup resistor to V
2. Communication speed in the table is an example to obtain a baud rate of 7200. Baud rate using external oscillator is bus frequency / 278.
3. External clock is an 4.0 MHz or 8.0 MHz crystal on OSC1 and OSC2 or a canned oscillator on OSC1.
4. X = don’t care
5. MON08 pin refers to P&E Microcomputer Systems’ MON08-Cyclone 2 by 8-pin connector.
