7.16 Port F (PF0~PF7)
PF read
(Function control)
Port F 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 function register PFFCx and the
control register PFCR. A reset allows all bits of PF, PFCR and PFFC1 to be cleared to "0,"
and the port F to be put in output disable mode.
Besides the input/output port function, the port F performs other functions: PF0 through
PF2, PF4 through PF6 have a serial communication function (SIO/UART ch0 and ch1).
If the port F is used as UART/SIO function port, select the function with the function register
of the corresponding port and set the open drain control register along with the serial
setting register. When the function registers 1 and 2 are set as the port, please do not set
any other function.
