5.2.11 Current Interrupt Level Management Register (CIL)
CIL is a specific function register (SFR) to manage the priority level of the interrupt currently being processed by the
CPU.
After maskable or non-maskable interrupts to which the priority levels are specified by the interrupt level control
registers (ILC0 to 7) is accepted by the CPU, corresponding bits of CIL are automatically set to "1", indicate the
currently processing interrupt level.
Upcoming interrrupts request to the CPU which have lower priority(lower level) will be disabled.
When the multiple bits are "1" in the CIL, it indicates the CPU is processing the multiple interrupts.
Each bit of CIL is automatically set to "1", so it has to be cleared by the software when the interrupt process has been
ended. Clear the bit once by writing an arbitrary data at the last in the interrupt process, which resets a flag of CIL
corresponding to the highest level.
See the section "5.3.6 How to program the interrupt process when the interrupt level control is enabled".
