Table 11-11 shows the recommended values for PLL configuration.
Field Name | Value | Description |
---|---|---|
PLL_CONTROL[4] HSDIV_SYSRESET | 0 | Allow power FSM to control |
PLL_CONTROL[3] PLL_SYSRESET | 0 | Allow power FSM to control |
PLL_GO[0] PLL_GO | 1–>0 | Write 1 when PLL is to be (re)locked with new parameters. This bit is cleared by hardware when the PLL request completes. |
PLL_CONFIGURATION2[20] HSDIVBYPASS | 0 | PLL controls HSDIVIDER bypass |
PLL_CONFIGURATION2[16] M4_CLOCK_EN or PLL_CONFIGURATION2[23] M6_CLOCK_EN or PLL_CONFIGURATION2[25] M7_CLOCK_EN | 1 | If PLL/HSDIVIDER is used as the clock source |
PLL_CONFIGURATION2[14] PHY_CLKINEN | 1 | Enable DCOCLK clock |
PLL_CONFIGURATION2[13] PLL_REFEN | 1 | Enable PLL reference |
PLL_CONFIGURATION2[10:9] PLL_LOCKSEL | 0x0 | Phase lock criteria to lock the PLL |
PLL_CONFIGURATION2[8] PLL_DRIFTGUARDEN | 0x0 | The RECAL status/interrupt must be used to decide when to perform a PLL uncalibration. No automatic uncalibration is performed. |
PLL_CONFIGURATION2[6] PLL_LOWCURRSTDBY | 0/1 | Set to 0 for fast PLL unlock, but higher standby current. Set to 1 for leakage level standby current, but longer unlock time. |
PLL_CONFIGURATION2[5] PLL_PLLLPMODE | 0 | Normal operation. For smaller display sizes, it may be possible to set to 1. |
PLL_CONFIGURATION2[0] PLL_IDLE | 0 | PLL active |
