Section 10 Interrupt Controller (INTC)
Table 10.11 IRL[3:0], IRL[7:4] Pins and Interrupt Levels
IRL interrupt detection requires a built-in noise-cancellation feature; that is, a mechanism to
ensure that transient level changes on the IRL pins are not detected as interrupts. For this purpose,
an IRL interrupt is not detected unless the levels sampled per bus-clock cycle remain unchanged
for four consecutive cycles.
The IRL interrupt priority level should be maintained until the CPU has accepted the interrupt and
started interrupt exception handling. It is possible to change the priority level to a higher priority.
When IRL level-encoded interrupts have been selected, usage or non-usage of the holding function
for interrupt requests can be selected by clearing or setting the LSH bit in ICR0. When usage of
the holding function has been selected (ICR0.LSH = 0), interrupt requests are held in the detection
circuit and the interrupt request must be cleared in the exception handling routine after acceptance
of the interrupt. For details, refer to section 10.7 Usage Notes. To select non-usage of the holding
function, set the LSH bit in ICR0 to 1. In this case, the operation of IRL level detection provides
upward compatibility with the level-encoded IRL interrupts on current SH-4 products.
