11.2.10. ADC Pre-Multiplexer
The ADC pre-multiplexer is a 16-to-1 multiplexer that selects between the 3 differential programmable gain amplifier
outputs, AB1 through AB9, temperature monitor signal (VTEMP), power monitor signal (VMON), and offset calibration
reference (VREF / 2). The ADC pre-multiplexer can be directly controlled or automatically scanned by the auto-sampling
sequencer.
When the ADC pre-multiplexer is automatically scanned, the unbuffered or sensitive signals should be masked by setting
appropriate register bits.
11.2.11. Configurable Analog Signal Matrix (CASM)
The CASM has 9 general purpose analog signals labeled AB1 through AB9 that can be used for:
 Routing the single-ended programmable gain amplifier or analog feed-through output to AB1 through AB9
 Routing an analog signal via AB1, AB2, or AB3 to the negative input of a general purpose comparator or
phase comparator
 Routing the 8-bit HP DAC output to AB2
 Routing the 10-bit LP DAC output to AB3
 Routing analog signals via AB1 through AB12 to the ADC pre-multiplexer
 Routing phase comparator feed-through signals to AB7, AB8, and AB9, and averaged voltage to AB1
11.2.12. Configurable Digital Signal Matrix (CDSM)
The CDSM has 7 general purpose bi-directional digital signals labeled DB1 through DB7 that can be used for:
 Routing the AIOx input to or output signals from DB1 through DB7
 Routing the general purpose comparator output signals to DB1 through DB7
