control and timing (continued)

configuration

Configuration data is stored in one 12-bit configuration register (CFR) (see Table 2 for CFR bit definitions). Once

configured after first power up, the information is retained in the H/W or S/W power down state. When the device

is being configured, a write CFR cycle is issued by the host processor. This is a 16-bit write. If the SCLK stops

after the first 8 bits are entered, then the next eight bits can be taken after the SCLK is resumed.

BIT

DEFINITION

D11

Reference select

0: External

1: Internal (Tie REFM to analog ground if the Internal reference is selected.)

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

D(4,3)

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).
