Table 6. Register Address Map

The following properties of the register address map should be noted:

• All register data is volatile.

• Data stored in locations TH1, TH2, TL1, TL2, IH1, IH2, IL1, IL2, HCFIG, ALMSCFIG, SCFIG, ALMHCFIG, VSET1,

VSET2, IDAC1, IDAC2, IODAC1, IODAC2, PGACAL, ADCCON, SSHUT, and LDAC can be loaded from EEPROM

at power-up or after a full reset.

• Write to the FIFO register only in LUT streaming mode (see the

LUT Streaming Mode

section).
