14 SUMMARY OF I/O PORTS AND ROM MASK OPTIONS
All standard quasi-bidirectional I/O ports are available; see “PCD33xxA Family”data sheet.
Port 0: 8 parallel port lines P0.0 to P0.7
Port 1: 8 parallel port lines P1.0 to P1.7
Port 2: 4 parallel port lines P2.0 to P2.3.
In addition to the standard ports, two derivative I/O ports are available:
Derivative Port 0: 6 parallel port lines DP0.0 to DP0.5 (register DP0L)
Derivative Port 1: 8 parallel port lines DP1.0 to DP1.7 (register DP1L).
The port options and the other ROM mask options are listed in Table 27. See Table 28 for the addresses of DP0L and
DP1L.

ROM mask options
Notes
1.
If standard (Option 1) or push-pull (Option 3) output is chosen, the P1.7/MDY output becomes a push-pull output.
If open-drain (Option 2) is chosen, the P1.7/MDY output becomes an open-drain output.
If standard (Option 1) or push-pull (Option 3) output is chosen, the DP1.7/DCO output becomes a push-pull output.
If open-drain (Option 2) is chosen, the DP1.7/DCO output becomes an open-drain output.
