General Device Information
Key to Pin Definitions
• Ctrl.: The output signal for a port pin is selected by bit field PC in the associated
register Px_IOCRy. Output O0 is selected by setting the respective bit field PC to
1x00_B, output O1 is selected by 1x01_B, etc.
Output signal OH is controlled by hardware.
• Type: Indicates the pad type and its power supply domain (A, B, M, 1).
– St: Standard pad
– Sp: Special pad e.g. XTALx
– DP: Double pad - can be used as standard or high speed pad
– In: Input only pad
– PS: Power supply pad

Ctrl. Type Function
3 TESTM
I
In/B Testmode Enable
Enables factory test modes, must be held HIGH for
normal operation (connect to V_DDPB).
An internal pull-up device will hold this pin high
when nothing is driving it.
4 P7.2
O0 / I St/B Bit 2 of Port 7, General Purpose Input/Output
EMUX0
O1 St/B External Analog MUX Control Output 0 (ADC1)
TxDC4

TxDC5
O3 St/B CAN Node 5 Transmit Data Output
CCU62_CCP I
OS0A
St/B CCU62 Position Input 0
TDI_C
IH St/B JTAG Test Data Input
If JTAG pos. C is selected during start-up, an
internal pull-up device will hold this pin high when
nothing is driving it.
5 TRST
I
In/B Test-System Reset Input
For normal system operation, pin TRST should be
held low. A high level at this pin at the rising edge
of PORST activates the XC2269I’s debug system.
In this case, pin TRST must be driven low once to
reset the debug system.
An internal pull-down device will hold this pin low
when nothing is driving it.
