Figure 58. Read While Converting versus Read While Sampling with Auto Nap Power-Down
Total Acquisition + Conversion Cycle Time:
Automatic: = 21 CCLKs
Manual: ≥ 21 CCLKs
Manual + deep ≥ 4SCLK + 100 µ s + 3 CCLK + 18 CCLK +16 SCLK + 1 µ s
power-down:
Manual + nap power-down: ≥ 4 SCLK + 3 CCLK + 3 CCLK + 18 CCLK +16 SCLK
Manual + auto nap ≥ 4 SCLK + 3 CCLK + 3 CCLK + 18 CCLK +16 SCLK (use wakeup to resume)
power-down:
Manual + auto nap ≥ 1 CCLK + 3 CCLK + 3 CCLK + 18 CCLK +16 SCLK (use CONVST to resume)
