Table 7. Mode Selection Signals
Primary reset input to the device. Asserting RSTI for at least 8 CPU
clock cycles immediately resets the CPU and peripherals.
Driven low for 1024 CPU clocks after the reset source has deasserted.
Table 6. PLL and Clock Signals
PLL disabled, clock driven by external oscillator
PLL disabled, clock driven by on-chip oscillator
PLL disabled, clock driven by crystal
PLL in normal mode, clock driven by external oscillator
Reserved
PLL in normal mode, clock driven by crystal
Crystal oscillator or external clock input except when the on-chip
relaxation oscillator is used.
Crystal oscillator output except when CLKMOD0=0, then sampled as
part of the clock mode selection mechanism.
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.
