(Function control)
The port L 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 PLCR and the
function register PLFCx. A reset allows all bits of the PL, PLCR, PLFC1 and PLFC2 to be
cleared to "0," and the port L to be put in output disable mode.
Besides the input/output port function, the port L performs other functions: PL0 and PL1
input 32-bit timer capture trigger. PL3 and PL7 output 32-bit timer compare match. PL4
through PL6 have HUART/HSIO function.
If the port L is used as a port HUART/HSIO function, 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.
