Timers
The Watchdog Timer ensures proper operation by
requiring periodic attention to prevent a reset-on-time-
out.
Two 16-bit timers operate as free-running down counters
or as periodic timers for fixed-interval interrupts and have
a range of 0.03 ms to 4.27 seconds.
One 32-bit timer, plus a 6-bit prescale counter, has a
range of 0.03
μ
s to 73.3 hours.
One 40-bit debug timer, plus a 6-bit prescale counter, has
a range of 1.0
μ
s to 12.7 days.
Interrupt Controller
The interrupt controller allows up to 64 interrupts to
generate an Interrupt Request (IRQ) or Fast Interrupt
Request (FIQ) signal to the processor core. Thirty-two
hardware priority assignments are provided for assisting
IRQ vectoring, and two levels are provided for FIQ
vectoring. This allows time-critical interrupts to be
processed in the shortest time possible. Internal
interrupts may be programmed as active high or active
low level sensitive inputs. External interrupts may be
programmed as active-high level-sensitive, active-low
level-sensitive,
rising-edge-triggered,
triggered, or combined rising/falling-edge-triggered.
falling-edge-
Supports 64 interrupts from a variety of sources (such
as UARTs, GPIO, and key matrix)
Routes interrupt sources to either the ARM920T’s
IRQ or FIQ (Fast IRQ) inputs
Four dedicated off-chip interrupt lines INT[3:0]
operate as level-sensitive interrupts
Any of the 16 GPIO lines maybe configured to
generate interrupts
Software-supported priority mask for all FIQs and
IRQs
Dual LED Drivers
Two pins are assigned specifically to drive external
LEDs.
General Purpose Input/Output (GPIO)
The 16 EGPIO pins may each be configured individually
as an output, an input, or an interrupt input.
There are 23 pins that may alternatively be used as input,
output, but do not support interrupts. These pins are:
Key Matrix ROW[7:0], COL[7:0]
Ethernet MDIO
Both LED Outputs
Two-wire Clock and Data
SLA [1:0]
6 pins may alternatively be used as inputs only:
CTSn, DSRn / DCDn
4 Interrupt Lines
2 pins may alternatively be used as outputs only:
RTSn
ARSTn
Reset and Power Management
The chip may be reset through the PRSTn pin or through
the open drain common reset pin, RSTOn.
Clocks are managed on a peripheral-by-peripheral basis
and may be turned off to conserve power.
The processor clock is dynamically adjustable from 0 to
200 MHz (184 MHz for industrial conditions).
