int set_tv_ldo_volt_a	(	uint8_t	channel,
		float	voltV
	)

Set LDO Output Channel x Target Output Voltage.

Bit 6:0. CNFG_LDO0_A (0x48) and CNFG_LDO1_A (0x4A)

Parameters:

[in]	channel	Channel number: 0 or 1.
[in]	voltV	LDO Output Channel x target output voltage field to be read. LDOx = 500mV + 25mV x TV_LDOx[6:0] 0.500V, 0.525V, 0.550V, 0.575V, 0.600V, 0.625V, 0.650V, 0.675V, 0.700V, ... 3.650, 3.675.

When TV_LDO[7] = 0, TV_LDO[6:0] sets the LDO's output voltage range from 0.5V to 3.675V. When TV_LDO[7] = 1, TV_LDO[6:0] sets the LDO's output voltage from 1.825V to 5V.

Returns:: 0 on success, error code on failure.
