4.1
Default pin functions
During and just after reset, all pins on ports 0-9 default to high-impedance input mode until
CPU firmware assigns other functions to the pins. This initial input mode routes all pins on ports
0-9 to be read as GPIO inputs as shown in the “Default Pin Function” column of Table 3.
Simultaneously, certain port pin signals are also routed to other functional inputs as shown in
the “Default Input Function” column of Table 3, and these pin input functions will remain until
CPU firmware makes other assignments. At any time, even after the CPU assigns pins to
alternate functions, the CPU may always read the state of any pin on ports 0-9 as a GPIO input.
CPU firmware may assign alternate functions to port pins as shown in columns “Alternate Input
1” or “Alternate Output 1, 2, 3” of Table 3 by writing to control registers at run-time.
Notes for Table 3:
Notes: 1 STMicroelectronics advises to ground, or pull up to VDDQ using a 100 K resistor, all unused
pins on port 0 - 9 to reduce noise susceptibility, noise generation, and minimize power
consumption. There are no internal or programmable pull-up resistors on ports 0-9.
2 All pins on ports 0 - 9 are 5V tolerant
3 Pins on ports 0,1,2,4,5,7,8,9 have 4 mA drive and 4mA sink. Ports 3 and 6 have 8 mA drive and
8 mA sink.
4 For 8-bit non-muxed EMI operation: Port 8 is eight bits of data, ports 7 and 9 are 16 bits of
address.
5 For 16-bit muxed EMI operation: Ports 8 and 9 are 16 bits of muxed address and data bits, port
7 is up to eight additional bits of high-order address
6 Signal polarity is programmable for interrupt request inputs, EMI_ALE, timer input capture
inputs and output compare/PWM outputs, motor control tach and emergency stop inputs, and
motor control phase outputs.
7 HiZ = High Impedance, V = Voltage Source, G = Ground, I/O = Input/Output
8 STR910F devices do not support USB. On these devices USBDP and USBDN signals are "Not
Used" (USBDN is not connected, USBDP must be pulled up by a 1.5K ohm resistor to VDDQ),
and all functions named “USB" are not available.
9 STR910F 128-pin devices do not support Ethernet. On these devices PHYCLK and all
functions named “MII*" are not available.
