only is valid. Consequently, when these bits are being set to 1, respective interrupt requests
will not be issued. Therefore, it is necessary to check these bits during the course of the
interrupt processing routine to have them cleared.
Also priority is given to the set and, when an interrupt cause occur while the a clearing
command (BCLR, MOV, etc.) is being executed, the CAPF bit and the SLW bit will not be
cleared respectively and it thus becomes necessary to pay attention to the clearing timing.
