11 / 110 page ![]() XC2287 / XC2286 / XC2285 XC2000 Family Derivatives General Device Information Preliminary Data Sheet 9 V0.91, 2007-02 Draft Version Notes to Pin Definitions 1. Ctrl.: The output signal for a port pin is selected via bitfield PC in the associated register Px_IOCRy. Output O0 is selected by setting the respective bitfield PC to 1x00 B, output O1 is selected by 1x01B, etc. Output signal OH is controlled by hardware. 2. Type: Indicates the employed pad type (St=standard pad, Sp=special pad, DP=double pad, In=input pad, PS=power supply) and its power supply domain (A, B, M, 1). Table 2 Pin Definitions and Functions Pin Symbol Ctrl. Type Function 3 TESTM IIn/B Testmode Enable Enables factory test modes, must be held HIGH for normal operation (connect to V DDPB). 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 TxDC4 O2 St/B CAN Node 4 Transmit Data Output CCU62_ CCPOS0A I St/B CCU62 Position Input 0 TDI_C I St/B JTAG Test Data Input 5 P8.4 O0 / I St/B Bit 4 of Port 8, General Purpose Input/Output CCU60_ COUT61 O1 St/B CCU60 Channel 1 Output TMS_D I St/B JTAG Test Mode Selection Input 6TRST IIn/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 XC228x’s debug system. In this case, pin TRST must be driven low once to reset the debug system. 7 P8.3 O0 / I St/B Bit 3 of Port 8, General Purpose Input/Output CCU60_ COUT60 O1 St/B CCU60 Channel 0 Output TDI_D I St/B JTAG Test Data Input |
