signals are regrouped in the F28044. At reset, EPWMMODE bits in the GPAMCFG register configure the
sync signals to be compatible to the TMS320F2808 device. In F28044 mode, the ePWMMODE bits are
set to 11 to select the EPWMA signals on all 16 GPIOs (GPIO0-GPIO15). This mode selection also
reconfigures the EPWM1 SYNCOUT to be connected to four groups of EPWM modules and as
EPWMSYNCO signals on the pin:
• Group 1: EPWM2, EPWM3, EPWM4
• Group 2: EPWM5, EPWM6, EPWM7, EPWM8
• Group 3: EPWM9, EPWM10, EPWM11, EPWM12
• Group 4: EPWM13, EPWM14, EPWM15, EPWM16
See the TMS320x28xx, 28xxx Enhanced Pulse Width Modulator (ePWM) User's Guide (SPRU791) for
additional details.
Table 4-2 through Table 4-5 show the complete ePWM register set per module.
