enabled on completion of the instruction, and so interrupt exception handling for that interrupt will
be executed on completion of the instruction. However, if there is an interrupt request of higher
priority than that interrupt, interrupt exception handling will be executed for the higher-priority
interrupt, and the lower-priority interrupt will be ignored. The same also applies when an interrupt
source flag is cleared to 0. The above conflict will not occur if an enable bit or interrupt source
flag is cleared to 0 while the interrupt is masked by the CPU.
(2) Instructions that Disable Interrupts
The instructions that disable interrupts 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.
(3) Interrupts during Execution of EEPMOV Instructions
Interrupt operation differs between the EEPMOV.B instruction and the EEPMOV.W instruction.
With the EEPMOV.B instruction, an interrupt request (including NMI) issued during the transfer
is not accepted until the transfer is completed.
With the EEPMOV.W instruction, if an interrupt request is issued during the transfer, interrupt
exception handling starts at the next break in the transfer cycle. The PC value saved on the stack in
this case is the address of the next instruction.
Therefore, if an interrupt is generated during execution of an EEPMOV.W instruction, the
following coding should be used.
