Functional Description
34.3 Functional Description
The Voltage Reference is a bandgap buffer system. Unity gain amplifiers are used.
The VREF_OUT signal is available as an internal reference when it is enabled. A 100 nF
capacitor must be connected between VREF_OUT and VSSA.
The following table shows all possible function configurations of the Voltage Reference.
34.3.1 Voltage Reference Disabled, SC[VREFEN] = 0
When SC[VREFEN] = 0, the Voltage Reference is disabled, all bandgap and buffers are
disabled. The Voltage Reference is in off mode.
34.3.2 Voltage Reference Enabled, SC[VREFEN] = 1
When SC[VREFEN] = 1, the Voltage Reference is enabled, and different modes can be
set by the SC[MODE_LV] bits.
