17.3.2.3 LIC Interrupt Status Registers
Each bit in the interrupt status registers corresponds to one interrupt source. In level mode, the
status bit continuously reflects the synchronized value of the interrupt source, and it is read-only.
In edge mode the status bit captures the active edge of the interrupt source, and can be cleared by
writing one to it. Writing zero has no effect. When an interrupt source is configured to second
edge detection mode, and the second edge appears while the status bit in LICAISR or LICBISR is
set, the appropriate second edge error status bit is set in LICAIESR or LICBIESR, and a second
edge interrupt is asserted at the PIC input.
Note:
If a status bit in LICAIESR or LICBIESR is set, it blocks the reassertion of the
corresponding status bit in LICAISR or LICBISR in second-edge mode.
