Table 7. External Interrupt Signals
Table 6. Mode Selection Signals
Primary reset input to the device. Asserting RSTI immediately resets
the CPU and peripherals.
Driven low for 512 CPU clocks after the reset source has deasserted.
Table 5. PLL and Clock Signals
External interrupt sources.
Crystal oscillator or external clock input.
Crystal oscillator output.
This output signal reflects the internal system clock.
The Serial Flash Programming mode is entered by asserting the
RCON pin (with the TEST pin negated) as the chip comes out of
reset. During this mode, the EzPort has access to the Flash memory
which can be programmed from an external device.
Reserved for factory testing only and in normal modes of operation
should be connected to VSS to prevent unintentional activation of
test functions.
