The 16-bit, read-only Interrupt Status Register (ISR) reflects the state of
the interrupt controller outputs to the CPU. Writes to this register have
no effect and are terminated normally.
INT — Normal Interrupt Request Flag
FINT — Fast Interrupt Request Flag
VEC[6:0] — Interrupt Vector Number Field
The read-only INT flag indicates whether the normal interrupt request
signal to the CPU is asserted or negated. Reset clears INT.
The read-only FINT flag indicates whether the fast interrupt request
signal to the CPU is asserted or negated. Reset clears FINT.
The read-only VEC[6:0] field contains the 7-bit interrupt vector
number (see
