IEP functional clock source selection:The clock source selection to the IEP module is done in register CTRLMMR_ICSSGn_CLKSEL[19-16] IEP_CLKSEL (where n = 0 or 1) in the CTRL_MMR0 location. For more information on these PRU_ICSSG level input clocks, refer to the PRU_ICSSG Integration.
Enhanced GPIO clock divider settings:In certain sample/shift clock settings of the PRU0 and PRU1 EGPIOs (when enabled in serial mode) two cascaded fractional dividers are done in the PR1_ICSSG_CFG top level configuration registers ICSSG_GPCFG0_REG and ICSSG_GPCFG1_REG. In addition, EGPIO clock active edge selection control can be exerted via the bit PRU0_GPI_CLK_MODE for PRU0 EGPIO and PRU1_GPI_CLK_MODE for the PRU1 EGPIO.
