Description: Write the target voltage 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_VOUT_IMM [REGULATOR=]<Regulator ID> [SEL=]<VSEL> [VOUT=]<Vout> [DELAY=]<Delay>[BYPASS=]<BYPASS>

'REGULATOR=', ''SEL=', 'VOUT=', 'DELAY=' and 'BYPASS=' are syntax options. When included, the parameters can be in any order.

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

VSEL selects the BUCKn_VSET1 or BUCKn_VSET2 bits which the command writes to if Regulator ID is BUCK1-5. VSEL is defined as: '0': BUCKn_VSET1, '1': BUCKn_VSET2, '2': Currently Active BUCKn_VSET, '3': Currently Inactive BUCKn_VSET. If Regulator ID is LDO1-4, VSEL value is ignored.

VOUT = output voltage in mV or V. Unit must be listed.

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. The delay value is 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.

BYPASS selects whether the selected LDO needs to operate in linear mode (BYPASS=0) or bypass mode (BYPASS=1)

Examples:

• REG_WRITE_VOUT_IMM BUCK3 2 1.05 V 100 µs — Sets BUCK3 to 1.05 V by updating the active BUCK3_VSET register after 100 µs
• REG_WRITE_VOUT_IMM REGULATOR=LDO1 SEL=0 VOUT=700 mV DELAY=6 ms BYPASS=0 — Sets LDO1 to 700 mV in linear mode after 6 ms.
• REG_WRITE_VOUT_IMM REGULATOR=LDO2 SEL=0 VOUT=3.3V DELAY=0 ms BYPASS=1 — Sets LDO2 to 3.3VV in bypass mode after 0 ms
