Interrupt Controller
PS015313-0508
Maskable Interrupts
The interrupt controller on the eZ80F92 device routes the interrupt request signals from
the internal peripherals and external devices (via the GPIO pins) to the CPU.
On the eZ80F92 device, all maskable interrupts use the CPU’s vectored interrupt function.
Table 11
maskable interrupt sources are listed in order of priority, with vector
est-priority interrupt. The full 16-bit interrupt vector is located at starting address {I[7:0],
IVECT[7:0]} where I[7:0] is the CPU’s Interrupt Page Address Register.
Table 11. Interrupt Vector Sources by Priority
Your program must store the starting address of the interrupt service routine (ISR) in the
two-byte interrupt vector locations. For example, for ADL mode the two-byte address for
the SPI interrupt service routine would be stored at {
1Fh
