All other pins are disconnected¹
1. Active Mode:
a. The following pins must be forced to V_DD: EA, RST, Port 0, and EW.
b. The following pins must be forced to V_SS: STADC, AV_ss, and AV_ref–.
c. Ports 1.6 and 1.7 should be connected to V_DD through resistors of sufficiently high value such that the sink current into these pins
cannot exceed the I_OL1 spec of these pins.
d. The following pins must be disconnected: XTAL2 and all pins not specified above.
