SFR Definition 6.8. ADC0TK: ADC0 Tracking Mode Select
SFR Address = 0xBA; SFR Page = 0x00;
6.4. Programmable Window Detector
The ADC Programmable Window Detector continuously compares the ADC0 output registers to user-pro-
grammed limits, and notifies the system when a desired condition is detected. This is especially effective in
an interrupt-driven system, saving code space and CPU bandwidth while delivering faster system
response times. The window detector interrupt flag (AD0WINT in register ADC0CN) can also be used in
polled mode. The ADC0 Greater-Than (ADC0GTH, ADC0GTL) and Less-Than (ADC0LTH, ADC0LTL)
registers hold the comparison values. The window detector flag can be programmed to indicate when mea-
sured data is inside or outside of the user-programmed limits, depending on the contents of the ADC0
Less-Than and ADC0 Greater-Than registers.

For BURSTEN = 0: ADC0 Power state controlled by AD0EN
For BURSTEN = 1, AD0EN = 1: ADC0 remains enabled and does not enter the
very low power state
For BURSTEN = 1, AD0EN = 0: ADC0 enters the very low power state and is
enabled after each convert start signal. The Power-Up time is programmed accord-
ing the following equation:
ADC0 Tracking Mode Enable Select Bits.
00: Reserved.
01: ADC0 is configured to Post-Tracking Mode.
10: ADC0 is configured to Pre-Tracking Mode.
11: ADC0 is configured to Dual Tracking Mode.
ADC0 Post-Track Time.
00: Post-Tracking time is equal to 2 SAR clock cycles + 2 FCLK cycles.
01: Post-Tracking time is equal to 4 SAR clock cycles + 2 FCLK cycles.
10: Post-Tracking time is equal to 8 SAR clock cycles + 2 FCLK cycles.
11: Post-Tracking time is equal to 16 SAR clock cycles + 2 FCLK cycles.
