Bit Field Type Reset Description
7 RESERVED R/W 0 Reserved for future use.
This bit can be written to and read from but it has no function. For compatibility with possible future device variants, it is recommended to program this bit to 0.
6 RANGE R/W 0 This bit selects the output voltage range.
0: Low range (1.800 V to 4.975 V)
1 : High range (2.025 V to 5.200 V)
5 ENABLE R/W X This bit controls operation of the converter.
0 : Converter operation disabled (Start-up value for TPS63811)
1 : Converter operation enabled (Start-up value for TPS63810)
4 RESERVED R/W 0 Reserved for future use.
This bit can be written to and read from but it has no function. For compatibility with possible future device variants, it is recommended to program this bit to 0.
3 FPWM R/W 0 This bit controls the forced-PWM function.
0: Forced-PWM operation disabled
1 : Forced-PWM operation enabled
2 RPWM R/W 0 This bit controls the ramp-PWM function.
0: Ramp-PWM operation disabled
1 : Ramp-PWM operation enabled
1:0 SLEW[1:0] R/W 00 These bits control the slew rate of the DVS function.
