• Pin out explanations:
— I/O is the sum of ports capable to act as digital input or output
For 112 Pin Versions:
Port A = 8, B = 8, E = 6 + 2 input only, H = 8, J = 4, K = 7, M = 8, P = 8, S = 8, T = 8,
PAD = 16 input only.
22 inputs provide Interrupt capability (H =8, P= 8, J = 4, IRQ, XIRQ
For 80 Pin Versions:
Port A = 8, B = 8, E = 6 + 2 input only, J = 2, M = 6, P = 7, S = 4, T = 8, PAD = 8 input only.
11 inputs provide Interrupt capability (P= 7, J = 2, IRQ, XIRQ)
