Chapter 6 Analog-to-Digital Converter (ATD10B16CV2)
6.2.1 AN15/ETRIG — Analog Input Channel 15 / External trigger Pin
This pin serves as the analog input channel 15. It can also be configured as general-purpose digital input
and/or external trigger for the ATD conversion.
6.2.2 ANx (x = 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0) — Analog Input
Channel x Pins
This pin serves as the analog input channel x. It can also be configured as general-purpose digital input .
6.2.3 V_RH, V_RL — High Reference Voltage Pin, Low Reference Voltage Pin
V_RH is the high reference voltage, V_RL is the low reference voltage for ATD conversion.
6.2.4 V_DDA, V_SSA — Analog Circuitry Power Supply Pins
These pins are the power supplies for the analog circuitry of the ATD10B16CV2 block.
