Table 3-8. Enhanced Capture Module (eCAP) Terminal Functions PIN NO SIGNAL NAME TYPE(1) PULL(2) MUXED DESCRIPTION PTP eCAP0 enhanced capture 0 ACLKX0/ECAP0/APWM0/GP2[12] 126 I/O IPD McASP0, GPIO input or auxiliary PWM 0 output. eCAP1 enhanced capture 1 ACLKR0/ECAP1/APWM1/GP2[15] 130 I/O IPD McASP0, GPIO input or auxiliary PWM 1 output. eCAP2 enhanced capture 2 ACLKR1/ECAP2/APWM2/GP4[12] 165 I/O IPD McASP1, GPIO input or auxiliary PWM 2 output. (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 3.6.7 Enhanced Pulse Width Modulators (eHRPWM0, eHRPWM1, eHRPWM2) Table 3-9. Enhanced Pulse Width Modulator (eHRPWM) Terminal Functions PIN NO SIGNAL NAME TYPE(1) PULL(2) MUXED DESCRIPTION PTP eHRPWM0 eHRPWM0 A output ACLKX1/EPWM0A/GP3[15] 162 I/O IPD (with high-resolution). McASP1, GPIO eHRPWM0 B AHCLKX1/EPWM0B/GP3[14] 160 I/O IPD output. McASP1, eHRPWM0 trip zone AMUTE1/EPWMTZ/GP4[14] 132 I/O IPD eHRPWM1, GPIO, input. eHRPWM2 Sync input to McASP1, eHRPWM0 module AFSX1/EPWMSYNCI/EPWMSYNCO/GP4[10] 163 I/O IPD eHRPWM0, GPIO or sync output to external PWM. eHRPWM1 eHRPWM1 A (with AXR1[8]/EPWM1A/GP4[8] 168 I/O IPD high-resolution). McASP1, GPIO eHRPWM1 B AXR1[7]/EPWM1B/GP4[7] 169 I/O IPD output. McASP1, eHRPWM1 trip zone AMUTE1/EPWMTZ/GP4[14] 132 I/O IPD eHRPWM0, GPIO, input. eHRPWM2 (1) I = Input, O = Output, I/O = Bidirectional, Z = High impedance, PWR = Supply voltage, GND = Ground, A = Analog signal.
