ADC0 SAR Conversion Clock Divider.
SAR Conversion clock is derived from FCLK by the following equation, where
AD0SC refers to the 5-bit value held in bits AD0SC[4:0]. SAR Conversion clock
requirements are given in Table 4.9.
BURSTEN = 0: FCLK is the current system clock.
BURSTEN = 1: FCLK is the 20 MHz low power oscillator, independent of the system
clock.
ADC0 8-Bit Mode Enable.
0: ADC0 operates in 10-bit mode (normal operation).
1: ADC0 operates in 8-bit mode.
ADC0 Track Mode.
Selects between Normal or Delayed Tracking Modes.
0: Normal Track Mode: When ADC0 is enabled, conversion begins immediately following the
start-of-conversion signal.
1: Delayed Track Mode: When ADC0 is enabled, conversion begins 3 SAR clock cycles fol-
lowing the start-of-conversion signal. The ADC is allowed to track during this time.
ADC0 Gain Control.
0: The on-chip PGA gain is 0.5.
1: The on-chip PGA gain is 1.
