Maskable Interrupt Processing
Note:
7.3.6 ”In-service priority register (ISPR)” on page 242
.
An INT input masked by the interrupt controllers and an INT input that occurs while another interrupt is
being processed (when PSW.NP = 1 or PSW.ID = 1) are held pending internally by the interrupt
controller. In such case, if the interrupts are unmasked, or when PSW.NP = 0 and PSW.ID = 0 as set by
the RETI and LDSR instructions, input of the pending INT starts the new maskable interrupt
processing.
