TLV2544/TLV2548 Configuration Register (CFR) Bit Definitions BIT DEFINITION D11 Reference select 0: External 1: internal D10 Internal reference voltage select 0: Internal ref = 4 V 1: internal ref = 2 V D9 Sample period select 0: Short sampling 12 SCLKs (1x sampling time) 1: Long sampling 24 SCLKs (2x sampling time) D(8–7) Conversion clock source select 00: Conversion clock = internal OSC 01: Conversion clock = SCLK 10: Conversion clock = SCLK/4 11: Conversion clock = SCLK/2 D(6,5) Conversion mode select 00: Single shot mode [FIFO not used, D(1,0) has no effect.] 01: Repeat mode 10: Sweep mode 11: Repeat sweep mode D(4,3)† TLV2548 TLV2544 Sweep auto sequence select 00: 0–1–2–3–4–5–6–7 01: 0–2–4–6–0–2–4–6 10: 0–0–2–2–4–4–6–6 11: 0–2–0–2–0–2–0–2 Sweep auto sequence select 00: N/A 01: 0–1–2–3–0–1–2–3 10: 0–0–1–1–2–2–3–3 11: 0–1–0–1–0–1–0–1 D2 EOC/INT – pin function select 0: Pin used as INT 1: Pin used as EOC D(1,0) FIFO trigger level (sweep sequence length) 00: Full (INT generated after FIFO level 7 filled) 01: 3/4 (INT generated after FIFO level 5 filled) 10: 1/2 (INT generated after FIFO level 3 filled) 11: 1/4 (INT generated after FIFO level 1 filled) † These bits only take effect in conversion modes 10 and 11. sampling The sampling period starts after the first 4 input data are shifted in if they are decoded as one of the conversion commands. These are select analog input (channel 0 through 7) and select test (channel 1 through 3). normal sampling When the converter is using normal sampling, the sampling period is programmable. It can be 12 SCLKs (short sampling) or 24 SCLKs (long sampling). Long sampling helps when SCLK is faster than 10 MHz or when input source resistance is high. |
