7.7 Port 6 (P60 through P67)
The port 6 is a general-purpose, 8-bit input/output port. For this port, inputs and outputs can be specified in units
of bits by using the control register P6CR and the function registers P6FC1, P6FC2 and P6FC3. A reset allows
all bits of the output latch P6 to be set to "1," all bits of P6CR, P6FC1, P6FC2 andP6FC3 to be cleared to "0,"
and the port 6 to be put in input mode.
Input is disabled right after reset. To enable input, set the corresponding bit of P6IE to “1”.
Besides the input/output port function, the port 6 performs other functions: P60 and P64 output SIO data, P61
and P65 input SIO data, P62 and P66 input and output SIO CLK or input CTS, P61 and P65 input external
interrupts, and P63 and P67 output a 16-bit timer.
The port 6 also functions as an address bus (A8 through A15). To access external memory, P6CR and P6FC1
must be provisioned to allow the port 6 to function as an address bus. The address bus function can be used only
in separate bus mode. (To put the port 6 in separate bus mode, the BUSMD pin (port 45) must be set to "L" level
during a reset.)
