All other pins are disconnected1
1. Active Mode:
a. The following pins must be forced to VDD: EA, RST, Port 0, and EW.
b. The following pins must be forced to VSS: STADC, AVss, and AVref–.
c. Ports 1.6 and 1.7 should be connected to VDD through resistors of sufficiently high value such that the sink current into these pins
cannot exceed the IOL1 spec of these pins.
d. The following pins must be disconnected: XTAL2 and all pins not specified above.
