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. The status of
the CFR can be read with a read CFR command when the device is programmed for one-shot conversion mode
(CFR D[6,5] = 00).
