IRQB
49
Input
(Schmitt)
External Interrupt Request B
—The IRQB input is an external interrupt
request that indicates that an external device is requesting service. It can be
programmed to be level-sensitive or negative-edge-triggered. If level-sensitive
triggering is selected, an external pull-up resistor is required for wired-OR
operation.
RESET
42
Input
(Schmitt)
Reset
—This input is a direct hardware reset on the processor. When RESET
is asserted low, the device is initialized and placed in the Reset state. A
Schmitt trigger input is used for noise immunity. When the RESET pin is
deasserted, the initial chip operating mode is latched from the external boot
pin. The internal reset signal will be deasserted synchronous with the internal
clocks, after a fixed number of internal clocks.
To ensure complete hardware reset, RESET and TRST should be asserted
together. The only exception occurs in a debugging environment when a
hardware device reset is required and it is necessary not to reset the
OnCE/JTAG module. In this case, assert RESET, but do not assert TRST.
EXTBOOT
39
Input
(Schmitt)
External Boot
—This input is tied to V
DD
to force device to boot from off-chip
memory. Otherwise, it is tied to V
SS
