*MODCLK signal is only recognized during reset
When the corresponding pin is congured for edge detection, a PORTFE bit is set if an edge is detected.
PORTFE bits remain set, regardless of the subsequent state of the corresponding pin, until cleared. To
clear a bit, rst read PORTFE, then write the bit to zero. When a pin is congured for general-purpose
I/O or for use as an interrupt request input, PORTFE bits do not change state.
This register determines which vector in the exception vector table is used for interrupts generated by
the port F edge-detect logic. Program PFIVR[7:0] to the value pointing to the appropriate interrupt vec-
tor. See the CPU16 section of this summary for interrupt vector assignments.
PFLVR determines the priority level of the port F edge-detect interrupt. The reset value is $00, indicating
that the interrupt is disabled. When several sources of interrupts from the SCIM are arbitrating for the
same level, the port F edge-detect interrupt has the lowest arbitration priority.
