Serial Port Sub-Block 0 Function Selection PINMUX1.SPBK0 BLOCK FUNCTION RESULTING PIN FUNCTIONS 00 GPIO (6) (default) GPIO: GP[104:99] 01 McBSP0 McBSP0: CLKX0, FSX0, DX0, CLKR0, FSR0, DR0 McASP0: ACLKR0, AFSR0, AHCLKR0, AXR0[3], 10 McASP0 Receive, 3 Serializers AXR0[2], AXR0[1] 11 Reserved Reserved Table 3-37. Serial Port Sub-Block 1 Function Selection PINMUX1.SPBK1 BLOCK FUNCTION RESULTING PIN FUNCTIONS 00 GPIO (6) (default) GPIO: GP[110:105] 01 McBSP1 McBSP1: CLKX1, FSX1, DX1, CLKR1, FSR1, DR1 McASP0 Transmit with 1 Serializer and McASP0: AXR0[0], ACLKX0, AFSX0, AHCLKX0, 10 Mute Control AMUTEIN0(1), AMUTE0 McBSP1: CLKX1, FSX1, DX1 11 McBSP1 Transmit, McASP0 SPDIF McASP0: AXR0[0], AHCLKX0, AMUTE0 (1) The input from the AMUTEIN0/FSX1/GP[109] pin is connected to both the McASP0 and GPIO. In addition, the VDD3P3V_PWDN.SP field determines the power state of the Serial Port Block pins. The Serial Port Block pins default to powered down and not operational. To use these pins, user must first program VDD3P3V_PWDN.SP = 0 to power up the pins. For more details on the VDD3P3V_PWDN.SP field, see Section 3.2, Power Considerations. To facilitate McASP0 operation, the input from the AMUTEIN0/FSX1/GP[109] pin is connected to both the McASP0 and the GPIO module. Therefore when an external mute event occurs, in addition to notifying the McASP0, it can also cause an interrupt through the GPIO module. Submit Documentation Feedback Device Configurations 125 |
