Port K (PK0~PK7)
The port K 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 PKCR and
the function register PKFCx. A reset allows all bits of the PK, PKCR and PKFC1 to be set to
"0," and the port K to be put in output disable mode.
Besides the input/output port function, the port K performs other functions: PK0 through
PK2 have a serial communication function (SIO/ UART ch8), PK5 through PK7 have a
serial bus I/F function (SBI2). PK3 and PK4 input 32-bit timer capture trigger (TC0IN and
TC1IN).
If the port K is used as a port UART/SIO function or serial bus I/F function, select the
function with the function register of the corresponding port and set the open drain control
register along with the select control register. When the function registers 1 and 2 are set as
the port, please do not set any other function.
