ePWM Registers
35.4 ePWM Registers
Table 35-22 lists the complete ePWM module control and status register set grouped by submodule. Each
register set is duplicated for each instance of the ePWM module. The base address for the control
registers is FCF7 8C00h for ePWM1, FCF7 8D00h for ePWM2, FCF7 8E00h for ePWM3, FCF7 8F00h for
ePWM4, FCF7 9000h for ePWM5, FCF7 9100h for ePWM6, and FCF7 9200h for ePWM7.
