The AS field is used during expanded memory access to
define the page register set to be used for instruction and
operand memory references. The PS field is used during
memory protect operations to define the access key used for
memory accesses. The PS field is also used during execution
of privileged Instructions - PS must be zero for such operations
to be legal. See Section 4.3 for further information on the use
of this field. The PB field is used in conjunction with the AS
field in 1750B mode to expand the number of page registers
available. Note that attempting to set AS or PB to a non-zero
value with no MMU, or setting PB to a non-zero value in 1750A
mode is illegal. This will be aborted and a fault 11 will be
generated (SW will remain unchanged).
3.4.2. PENDING INTERRUPT REGISTER (PI)
This 16-bit register is used to capture and hold interrupts
until they can be processed by microcode and user software. A
logic 1 is used to represent an active pending interrupt. The Pl
register supports three dedicated external, six user-definable
external, and seven dedicated internal interrupts. Level-
sensitive interrupts are sampled on each rising CLK edge,
whilst edge sensitive interrupts are captured immediately.
