NOTE:
This output signal is used as a connection to drive an external crystal
when the internal oscillator circuit is used. XTAL should be grounded
when using an external clock input on EXTAL.
This output signal reflects the internal system clock.
This is an active high signal only required during reset if chip
configuration is performed. If this signal is pulled high during reset, then
the PLL will be used to clock the device. Pulling this signal low during
reset selects external clock mode. See
During
In addition to the functions stated here, these signals can also be
configured for discrete I/O.
These three-state bidirectional signals provide the general-purpose data
path between the microcontroller unit (MCU) and all other devices.
Some of these pins are used during reset for chip configuration.
This output signal is used in emulation mode as a strobe for capturing
addresses, controls, and data during show cycles. This signal is also
used as RCON.
The RCON signal, used only during reset, indicates whether the states
on the external signals affect the chip configuration.
