Bold, italicized pin names indicate pin functions at reset.
Valid only if the I/O function is selected on the pin
§If the GPIO pin is configured as an output, these bits can be written to. If the pin is configured as an input, these bits are read from.
If the DIR bit is 0, the GPIO pin functions as an input. For a value of 1, the pin is configured as an output.
#At reset, all LF240x devices come up with the W/R/IOPC0 pin in W/R mode. On devices that lack an external memory interface (e.g., LF2406
and LF2402), W/R mode is not functional and MCRB.0 must be set to a 0 if the IOPC0 pin is to be used.
||Note that bits 15 through 9 of the MCRB register
must
be written as 1 only. Writing a 0 to any of these bits will cause unpredictable operation
of the device.
