EMB_A[8]/GP7[10] D12 O IPD EMB_A[7]/GP7[9] A11 O IPD EMB_A[6]/GP7[8] B11 O IPD EMB_A[5]/GP7[7] C11 O IPD (1) I = Input, O = Output, I/O = Bidirectional, Z = High impedance, PWR = Supply voltage, GND = Ground, A = Analog signal. Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the the signal name highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different types (ie., input versus output), the table reflects the pin function direction for that particular peripheral. (2) IPD = Internal Pulldown resistor, IPU = Internal Pullup resistor Copyright © 2010, Texas Instruments Incorporated Device Overview 19 Submit Documentation Feedback Product Folder Link(s): AM1707 |
