PIN_ADDR

Undefined
Address of the analog signal (pin) to be sampled by
this channel
- 0..31 : Vout = AN0..31, select corresponding analog
input
- 32: Vout = Vmotor, select motor input
- 33: Vout = Vaux, select auxiliary input
- 34: Vout = AmuxbusA
- 35: Vout = AmuxbusB
- 36: Vout = Vccd
- 37: Vout = Vdda
- 38: Vout = Vbg, Bandgap voltage from SRSS
- 39: Vout = Vtemp, select temperature sensor. Make
sure that only 1 ADC is allowed to use this.
- 40..61: Vout = undefined, reserved for future products
- 62: Vout = VrefL (VrefL actually bypasses the
SARMUX (XSL))
- 63: Vout = VrefH (VrefH actually bypasses the
SARMUX (XSH))
Note: When PORT_ADDR is not set to SARMUX0, pin
addresses from 32-63 are not available. Only
addresses 0-31 can be accessed from SARMUX1-3

PORT_ADDR
RW
R
Undefined
Select the physical port. This field is only valid for
ADC0.
ADC0 can control and connect to the SARMUX of the
neighboring ADC1-3. This requires the corresponding
ADC to be off while the SARMUX is left on.
When ADC0 controls another SARMUX it uses the
PIN_ADDR, EXT_MUX_EN/SEL of this channel to
control the other SARMUX.
SARMUX0
0
ADC uses it's own SARMUX
SARMUX1
1
ADC0 uses SARMUX1 (only valid for ADC0, undefined
result if used for ADC1-3)
