SW_VOUT Bits: Use SYS_SEL and SYS_VOUT bits to set the output on SYS. The SYS voltage is calculated using the following equation: See table below for all VOUT values that can be programmed through SYS_SEL and SYS_VOUT. If SYS_SEL = 01, then SYS = 1.30 V + SYS_VOUTCODE x 100 mV. If SYS_SEL = 11, then SYS = 1.80 V + SYS_VOUTCODE x 100 mV. |
