There is no direct software gate control for the DPLL_SATA.CLKDCOLDO output.
The DPLL_SATA.CLKDCOLDO clock output is automatically gated (CLKDCOLDO pulled low) in the following scenarios:
- DPLL power-up sequence. For more information on the power-up sequence, see Section 28.1.4.3.6.1, SATA Clock Generator Power Up.
- DPLL entering a relock sequence. For more information on the relocking sequence, see Section 28.1.4.3.6.2, SATA DPLL Sequences.
- DPLL entering idle-bypass low-power mode. For more information on idle-bypass mode, see Section 28.1.4.3.6.4, SATA DPLL Idle-Bypass Mode.
- DPLL entering MN-bypass mode. For more information on MN-bypass mode, see Section 28.1.4.3.6.5, SATA DPLL MN Bypass Mode.
