2-byte and N-byte transfers, respectively. The operation for a
3-byte transfer can be inferred from these diagrams.
SPI Configuration
ADDRESS 0X00: CHIP_PORT_CONFIG
Bit ordering and SPI reset are controlled by this register. Bit
order can be selected as MSB to LSB (MSB first) or LSB to
MSB (LSB first) to accommodate various microcontrollers.
Bit 7 SDO Active
Bit 6 LSB First
Setting this bit high configures the SPI to interpret serial
data as arriving in LSB to MSB order.
Bit 5 Soft Reset
Setting this bit high resets all SPI registers to default values.
Bit 4 Reserved
This bit should always be set high.
Bits 3:0 These bits should always mirror bits 4:7 to avoid
ambiguity in bit ordering.
ADDRESS 0X02: BURST_END
If a series of sequential registers are to be set, burst mode
can improve throughput by eliminating redundant
addressing. In three-wire SPI mode the burst is ended by
pulling the CSB pin high. If the device is operated in two-wire
mode the CSB pin is not available. In that case, setting the
burst_end address determines the end of the transfer.
During a write operation, the user must be cautious to
transmit the correct number of bytes based on the starting
and ending addresses.
Bits 7:0 Burst End Address
This register value determines the ending address of the
burst data.
Device Information
ADDRESS 0X08: CHIP_ID
ADDRESS 0X09: CHIP_VERSION
The generic die identifier and a revision number,
respectively, can be read from these two registers.
Indexed Device Configuration/Control
ADDRESS 0X10: DEVICE_INDEX_A
A common SPI map, which can accommodate
single-channel or multi-channel devices, is used for all
Intersil ADC products. Certain configuration commands
(identified as Indexed in the SPI map) can be executed on a
per-converter basis. This register determines which
converter is being addressed for an Indexed command. It is
important to note that only a single converter can be
addressed at a time.
This register defaults to 00h, indicating that no ADC is
addressed. Error code ‘AD’ is returned if any indexed
register is read from without properly setting
device_index_A.
ADDRESS 0X20: OFFSET_COARSE
ADDRESS 0X21: OFFSET_FINE
The input offset of each ADC core can be adjusted in fine
and coarse steps. Both adjustments are made via an 8-bit
word as detailed in Table 7.
