Figure 3-26 shows the software warm reset sequence of the DSP2 subsystem.
Before asserting the software reset to the DSP subsystem, the MPU software must ensure that:
The software reset sequence is:
- MPU software sets the RM_DSP2_RSTCTRL[1] RST_DSP2 = 0 and RM_DSP2_RSTCTRL[0] RST_DSP2_LRST = 1. This causes the PRCM module to assert DSP2_RST, DSP2_LRST to the DSP subsystem. The DSP2_PWRON_RST remains deasserted.
- The MPU software enables the functional clock to the DSP subsystem.
- The MPU software cleares theRM_DSP2_RSTCTRL[1] RST_DSP2 and RM_DSP2_RSTCTRL[0] RST_DSP2_LRST bits. This causes the PRCM module to release DSP2_RST and DSP2_LRST to the DSP subsystem.
