1. Bits 1 and 0 are supplied by the QADC.
The FRZ bit determines whether or not the QADC responds to assertion of the IMB
FREEZE signal.
The SUPV bit designates the assignable space as supervisor or unrestricted.
The IARB field is used to arbitrate between simultaneous interrupt requests of the
same priority. Each module that can generate interrupt requests must be assigned a
unique, non-zero IARB field value.
Used for factory test only.
When queue 1 generates an interrupt request, IRLQ1[2:0] determines which of the
interrupt request signals is asserted. When a request is acknowledged, the QADC
compares IRLQ1[2:0] to a mask value supplied by the CPU32 to determine whether
to respond. IRLQ1[2:0] must have a value in the range of $0 (interrupts disabled) to $7
(highest priority).
When queue 2 generates an interrupt request, IRLQ2[2:0] determines which of the
interrupt request signals is asserted. When a request is acknowledged, the QADC
compares IRLQ2[2:0] to a mask value supplied by the CPU32 to determine whether
to respond. IRLQ2[2:0] must have a value in the range of $0 (interrupts disabled) to $7
(highest priority).
0 = QADC ignores the IMB FREEZE signal.
1 = QADC finishes any current conversion, then freezes.
0 = Only the module configuration register, test register, and interrupt register are
1 = All QADC registers and tables are designated as supervisor-only data space.
