(Function control)
The port N is a general-purpose, 8-bit input/output port. For this port, inputs and outputs
can be specified in units of bits. Outputs can be set by using the control register PNCR and
the function register PNFCx. A reset allows all bits of the PN, PNCR, PNFC1 and PNFC2 to
be cleared to "0," and the port N to be put in output disable mode.
Besides the input/output port function, the port N performs other functions: PN0 through
PN2 input external interrupt (INT6~INT8). PN3 and PN7 input A/D converter external start
request.
