PGE Enhanced Pulse-Width Modulator Modules (ePWM) (continued) Terminal Signal Reset Pull Pull Type Description Type State Signal Name 144 PGE MIBSPI3NCS[3]/I2C_SCL/N2HET1[29]/nTZ1 3 Input Pull Up Fixed 20 µA Trip Zone Inputs 1, 2 and Pull Up 3. These signals are MIBSPI3NCS[2]/I2C_SDA/N2HET1[27]/nTZ2 4 either connected N2HET1[10]/nTZ3 118 Pull Down asynchronously to the ePWMx trip zone inputs, or double-synchronized with VCLK4, or double- synchronized and then filtered with a 6-cycle VCLK4-based counter before connecting to the ePWMx trip zone inputs. 4.3.1.6 General-Purpose Input / Output (GPIO) Table 4-6. PGE General-Purpose Input / Output (GPIO) Terminal Signal Reset Pull Pull Type Description Type State Signal Name 144 PGE GIOA[0] 2 I/O Pull Down Programmable, General-purpose I/O. 20 µA All GPIO terminals are GIOA[1] 5 capable of generating GIOA[2]/N2HET2[0] /EQEP2I 9 interrupts to the CPU on rising / falling / both GIOA[5]/EXTCLKIN/EPWM1A/N2HET1_PIN_nDIS 14 edges. GIOA[6]/N2HET2[4]/EPWM1B 16 GIOA[7]/N2HET2[6]/EPWM2A 22 GIOB[0] 126 GIOB[1] 133 GIOB[2] 142 MIBSPI3NCS[0]/AD2EVT/GIOB[2]/ 55(1) Pull Up EQEP1I/N2HET2_PIN_nDIS GIOB[3] 1 Pull Down (1) GIOB[2] cannot output a level on to pin 55. Only the input functionality is supported so that the application can generate an interrupt whenever the N2HET2_PIN_nDIS is asserted (driven low). Also, a pull up is enabled on the input. This is not programmable using the GIO module control registers. 4.3.1.7 Controller Area Network Controllers (DCAN) Table 4-7. PGE Controller Area Network Controllers (DCAN) Terminal Signal Reset Pull Pull Type Description Type State Signal Name 144 PGE CAN1RX 90 I/O Pull Up Programmable, CAN1 receive, or GPIO 20 µA CAN1TX 89 CAN1 transmit, or GPIO CAN2RX 129 CAN2 receive, or GPIO CAN2TX 128 CAN2 transmit, or GPIO CAN3RX 12 CAN3 receive, or GPIO CAN3TX 13 CAN3 transmit, or GPIO 16 Terminal Configuration and Functions Copyright © 2012–2015, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS570LS1114 |
