The same also applies when an interrupt source flag is cleared to 0.
The above contention will not occur, if an enable bit or interrupt source flag is cleared to 0 while
the interrupt is masked.
Figure 5.9 shows an example in which the CMIEA bit in the TCR register of the 8-bit timer is
cleared to 0.
5.6.2
The instructions that disable interrupt requests directly after execution are LDC, ANDC, ORC,
and XORC. After any of these instructions are executed, all interrupts including NMI are disabled
and the next instruction is always executed.
When the I bit is set by one of these instructions, the new value becomes valid two states after
execution of the instruction ends.
5.6.3
There are times when interrupt acceptance is disabled by the interrupt controller.
