MCP3910 INTERNAL
REGISTERS
The addresses associated with the internal registers
are listed in Table 9-1. This section also describes the
registers in detail. All registers are 24-bit long registers,
which can be addressed and read separately.
The format of the data registers (0x00 to 0x01) can be
changed with the WIDTH_DATA[1:0] bits in the
STATUSCOM register. The READ[1:0] and WRITE bits
define the groups and types of registers for continuous
read/write communication or looping on address sets,
as shown in Table 9-2.
