Description
DIO pins. If unused, these pins must be configured as DIOs and
set to outputs by the firmware.
Emulator port pins (when ICE_E pulled high) .
ICE enable. When zero, E_RST, E_TCLK, and E_RXTX are disable
For production units, this pin should be pulled to GND to disable the
emulator port. This pin should be brought out to the programming
interface in order to create a way for reprogramming parts that have
the SECURE bit set.
Clock PLL output.
Digital output test multiplexer.
This input pin resets the chip into a known state. For normal
operation, this pin is connected to GND. To reset the chip, this pin
should be pulled high. No external reset circuitry is necessary. Direct
connect to ground in normal operation.
UART input. If unused, this pin must be terminated to V3P3 or
GND.
UART output.
Enables Production Test. Must be grounded in normal operation.
