P1.7鈭?: General purpose I/O port. Most instructions will read the port pins in case of a port read
access, however in case of read-modify-write instructions, the port latch is read. Some pins
also have alternate input or output functions. This alternate functions are described below:

Port 4 alternate modes.
=00: Mode 0. P4.x is a general purpose I/O port which is the same as Port 1.
=01: Mode 1. P4.x is a Read Strobe signal for chip select purpose. The address
range depends on the SFR P4xAH, P4xAL and bits P4xC1, P4xC0.
=10: Mode 2. P4.x is a Write Strobe signal for chip select purpose. The address
range depends on the SFR P4xAH, P4xAL and bits P4xC1, P4xC0.
=11: Mode 3. P4.x is a Read/Write Strobe signal for chip select purpose. The
address range depends on the SFR P4xAH, P4xAL and bits P4xC1, P4xC0
P4xC1, P4xC0
Port 4 Chip-select Mode address comparison:
=00: Compare the full address (16 bits length) with the base address registers
P4xAH and P4xAL.
=01: Compare the 15 high bits (A15-A1) of address bus with the base address
registers P4xAH and P4xAL.
=10: Compare the 14 high bits (A15-A2) of address bus with the base address
registers P4xAH and P4xAL.
=11: Compare the 8 high bits (A15-A8) of address bus with the base address
registers P4xAH and P4xAL.
