Figure 3-33 shows the power-on reset sequence of the EVE1 subsystem.
The power-on reset to EVE1 is applied when PD_EVE1 is powered. The assumptions on power-on reset assertion are:
- The PRCM module provides the EVE1_GFCLK functional clock to the EVE subsystem, and it has been enabled by MPU software control.
The power-on reset sequence is:
- Software clears the RM_EVE1_RSTCTRL[1] RST_EVE1 bit. This causes the PRCM module to release the EVE1_PWRON_RST and the EVE1_RST signals. Then software can download data into TCM memory while keeping the sequencer CPUs under reset.
- When the TCM memory is initialized, software clears the RM_EVE1_RSTCTRL[0] RST_EVE1_LRST bit .This release EVE1_LRST to the local CPU inside EVE subsystem.
