2.1 Sysconfig Settings for EPI

This section is to generate the initialization code of EPI peripheral using sysconfig tool. Detailed specs for EPI IP can be found in the AM13E230 TRM [6] EPI section. The code generated can be found in file <ti_sdk_dl_config.c> and called in SYSCFG_DL_init function in main function. To read more about EPI in detail, please refer to the AM13x academy chapter for EPI attached in the References section.

There are 2 key specs to be configured: refresh count and EPI clock divider.
