Description: Write the operation mode of a specified regulator after a specified delay. This command is a spin-off of the REG_WRITE_IMM command with the intention to save instruction bits.

Assembly command: REG_WRITE_VCTRL_IMM [REGULATOR=]<Regulator ID> [VCTRL=]<VCTRL> [MASK=]<Mask> [DELAY=]<Delay> [DELAY_MODE=]<Delay Mode>

'REGULATOR=', 'VCTRL=', 'MASK=', and 'DELAY=' are options. When included, the parameters can be in any order.

Regulator ID = BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, LDO1, LDO2, LDO3, or LDO4.

VCTRL = 0-15, in hex, decimal, or binary format. Data to write to the following regulator control fields:

• BUCKs: BUCKn_PLDN, BUCKn_VMON_EN, BUCKn_VSEL, BUCKn_FPWM_MP, BUCKn_FPWM, and BUCKn_EN
• LDOs: LDOn_PLDN, LDOn_VMON_EN, 0, 0, LDOn_EN

DELAY = delay time in ns, µs, ms, or s. If no unit is entered, this field must be an integer value between 0-63, which becomes the threshold count for the counter running a step size specified in the register PFSM_DELAY_STEP. Delay value is be rounded to the nearest achievable delay time based on the current step size. Current step size is based on the default NVM setting or a SET_DELAY value from a previous command in the same sequence. Assembler reports an error if the step size is too large or too small to meet the delay.

Delay Mode must be one of the below options: MATCH_EN = 0 (Delay if VCTRL enable bit mismatches) MATCH_ALL = 1 (Delay if any VCTRL bits mismatch) ALWAYS = 2 (Delay always)

Examples:

• REG_WRITE_VCTRL_IMM BUCK3 0x00 0xE0 100 µs — Sets BUCK3 to OFF (VCTRL bits = 0b00000) after 100 µs
• REG_WRITE_VCTRL_IMM REGULATOR=LDO1 VCTRL=0x09 MASK=0x36 DELAY=10 ms — Set LDO1_VMON and LDO1_EN to '1' after 10 ms
