Description
Extended mode (16-bit data bus):
The port functions as the data bus regardless of
the values in these bits.
Single-chip mode/extended mode (8-bit data bus):
If port 6 pins are specified for use as the general
I/O port, the corresponding port 6 pins are output
ports when the P6DDR bits are set to 1, and input
ports when cleared to 0.
Description
Extended mode (16-bit data bus):
If a port 6 read is performed while the P6DDR bits
are set to 1, the P6DR values are read. If a port 6
read is performed while the P6DDR bits are
cleared to 0, 1 is read.
Single-chip mode/extended mode (8-bit data bus):
P6DR stores output data for the port 6 pins that
are used as the general output port.
If a port 6 read is performed while the P6DDR bits
are set to 1, the P6DR values are read. If a port 6
read is performed while the P6DDR bits are
cleared to 0, the pin states are read.
