VECINT: Vector Interrupt Register (Addr:FF92)
This register contains a vector value, which identifies the internal interrupt source that trapped to location
0003H
.
Writing (any value) to this register removes the vector and updates the next vector value (if another interrupt is
pending). Note: the vector value is offset; therefore, its value is in increments of two (bit 0 is set to 0). When no interrupt
is pending, the vector is set to 00h (see Table 9
2). As shown, the interrupt vector is divided to two fields: I[2:0] and
G[3:0]. The I field defines the interrupt source within a group (on a first-come-first-served basis). In the G field, which
defines the group number, group G0 is the lowest, and G15 is the highest priority.

I[2:0]
0H
This field defines the interrupt source in a given group. See Table 9
2. Bit 0 = 0 always; therefore, vector values
are offset by two.

G[3:0]
0H
This field defines the interrupt group. I[2:0] and G[3:0] combine to produce the actual interrupt vector.
