19.2 Interrupt
19.2.1 Reading Address 00000
19.2.2 SP Setting
19.2.3 External Interrupt and Key Input Interrupt
19.2.4 Watchdog Timer Interrupt
________
Do not read the address 00000
the CPU reads interrupt information (interrupt number and interrupt request level) from 00000
interrupt sequence. At this time, the acknowledged interrupt IR bit is set to “0”.
If the address 00000
among the enabled interrupts is set to “0”. This may cause a problem that the interrupt is canceled, or
an unexpected interrupt is generated.
Set any value in the SP before an interrupt is acknowledged. The SP is set to “0000
Therefore, if an interrupt is acknowledged before setting any value in the SP, the program may run out
of control.
Either an “L” level or an ”H” level of at least 250ns width is necessary for the signal input to the INT
INT
Reset the watchdog timer after a watchdog timer interrupt is generated.
