: Interrupt request flag is not cleared by the interrupt clear signal.
: Interrupt request flag is cleared by the interrupt clear signal.
: Interrupt request flag is cleared by the interrupt clear signal (stop request present) .
*1 : The Flash write/erase, timebase timer, and watch timer cannot be used at the same time.
*2 : When the 16-bit reload timer underflow interrupt is changed from enable (TMCSR : INTE
= 1) to disable
(TMCSR : INTE
= 0) , disable the interrupt in the interrupt control register (ICR12 : IL2 to 0 : 111B) , then set
the INTE bit to 0.
Note : If there are two interrupt sources for the same interrupt number, the resource will clear both interrupt request
flags at the EI2OS/
DMAC interrupt clear signal. Therefore if either of the two sources uses the EI2OS/
DMAC function, the other interrupt function cannot be used. The interrupt request enable bit for the corre-
sponding resource should be set to “0” and interrupt requests from that resource should be handled by
software polling.
