Pin Description
V_CC
: PIN 40 (DIP40), PIN 44 (PLCC44)
Supply voltage during normal, Idle and power down operations.
V_SS
: PIN 20 (DIP40), PIN 22 (PLCC44)
Circuit ground.
Port 0
: PIN 32~39 (DIP40), PIN 36~43 (PLCC44)
Port 0 is an 8bit open drain bi-directional I/O port. Port 0 pins that have 1's
written to the them float, and in that state can be used as high impedance inputs.
Port 0 is also the multiplexed low-order address and data bus during accesses to
external program and data memory.
In this application it uses strong internal pullups when emitting 1's.
