When FSOURCES[n] is 0, the corresponding discharge current source behavior depends on SOURCES[n].
When FSOURCES[n] is 1, the corresponding discharge current source is forced to be enabled continuously. This is useful for
testing or debugging but should not be done during normal acquisition.
0: The current source module is globally disabled.
1: The current source module is globally enabled.
0: The voltage for the reference resistor is generated from the internal band gap circuit.
1: The voltage for the reference resistor is VDDIO/2.
0: The reference current flows through an external resistor on the DIS pin.
1: The reference current flows through the internal reference resistor.
This field is used to trim the discharge current. 0x00 corresponds to the minimum current value, and 0x1F corresponds to the
maximum current value.
When SOURCES[n] is 0, the corresponding discharge current source is disabled.
When SOURCES[n] is 1, the corresponding discharge current source is enabled at appropriate times during acquisition.
