Signal Descriptions (continued) NAME PIN NO. DESCRIPTION (1) PGF, PTP PIN # ZHH BALL # ZJZ BALL # GPIO6 EPWM4A EPWMSYNCI EPWMSYNCO 13 E1 F1 General-purpose input/output 6 (I/O/Z) Enhanced PWM4 output A and HRPWM channel (O) External ePWM sync pulse input (I) External ePWM sync pulse output (O) GPIO7 EPWM4B MCLKRA ECAP2 16 F2 F2 General-purpose input/output 7 (I/O/Z) Enhanced PWM4 output B (O) McBSP-A receive clock (I/O) Enhanced capture input/output 2 (I/O) GPIO8 EPWM5A CANTXB ADCSOCAO 17 F1 F3 General-purpose Input/Output 8 (I/O/Z) Enhanced PWM5 output A and HRPWM channel (O) Enhanced CAN-B transmit (O) ADC start-of-conversion A (O) GPIO9 EPWM5B SCITXDB ECAP3 18 G5 G1 General-purpose input/output 9 (I/O/Z) Enhanced PWM5 output B (O) SCI-B transmit data(O) Enhanced capture input/output 3 (I/O) GPIO10 EPWM6A CANRXB ADCSOCBO 19 G4 G2 General-purpose input/output 10 (I/O/Z) Enhanced PWM6 output A and HRPWM channel (O) Enhanced CAN-B receive (I) ADC start-of-conversion B (O) GPIO11 EPWM6B SCIRXDB ECAP4 20 G2 G3 General-purpose input/output 11 (I/O/Z) Enhanced PWM6 output B (O) SCI-B receive data (I) Enhanced CAP Input/Output 4 (I/O) GPIO12 TZ1 CANTXB MDXB 21 G3 H1 General-purpose input/output 12 (I/O/Z) Trip Zone input 1 (I) Enhanced CAN-B transmit (O) McBSP-B transmit serial data (O) GPIO13 TZ2 CANRXB MDRB 24 H3 H2 General-purpose input/output 13 (I/O/Z) Trip Zone input 2 (I) Enhanced CAN-B receive (I) McBSP-B receive serial data (I) GPIO14 25 H2 H3 General-purpose input/output 14 (I/O/Z) TZ3/XHOLD Trip Zone input 3/External Hold Request. XHOLD, when active (low), requests the external interface (XINTF) to release the external bus and place all buses and strobes into a high- impedance state. To prevent this from happening when TZ3 signal goes active, disable this function by writing XINTCNF2[HOLD] = 1. If this is not done, the XINTF bus will go into high impedance anytime TZ3 goes low. On the ePWM side, TZn signals are ignored by default, unless they are enabled by the code. The XINTF will release the bus when any current access is complete and there are no pending accesses on the XINTF. (I) SCITXDB SCI-B Transmit (O) MCLKXB McBSP-B transmit clock (I/O) GPIO15 26 H4 J1 General-purpose input/output 15 (I/O/Z) TZ4/XHOLDA Trip Zone input 4/External Hold Acknowledge. The pin function for this option is based on the direction chosen in the GPADIR register. If the pin is configured as an input, then TZ4 function is chosen. If the pin is configured as an output, then XHOLDA function is chosen. XHOLDA is driven active (low) when the XINTF has granted an XHOLD request. All XINTF buses and strobe signals will be in a high-impedance state. XHOLDA is released when the XHOLD signal is released. External devices should only drive the external bus when XHOLDA is active (low). (I/O) SCIRXDB SCI-B receive (I) MFSXB McBSP-B transmit frame synch (I/O) GPIO16 SPISIMOA CANTXB TZ5 27 H5 J2 General-purpose input/output 16 (I/O/Z) SPI slave in, master out (I/O) Enhanced CAN-B transmit (O) Trip Zone input 5 (I) |
