RSTI
Primary reset input to the device. Asserting RSTI for at least 8 CPU
clock cycles immediately resets the CPU and peripherals.

Reset Out
RSTO
Driven low for 1024 CPU clocks after the reset source has deasserted.

XTAL
Crystal oscillator output except when CLKMOD0=0, then sampled as
part of the clock mode selection mechanism.

Clock Mode Selection
CLKMOD[1:0]
Selects the clock boot mode.

Reset Configuration
RCON
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.
Test
TEST
Reserved for factory testing only and in normal modes of operation
should be connected to VSS to prevent unintentional activation of
test functions.
