5.2 Internal Registers
Registers provide direct control and status of the part. These registers are
accessed by the serial programming interface described in this section. Table 5-2
provides a register bit map. Table 5-3 lists the alpha-sorted register index.
Section 5.4 gives bit descriptions and detailed programming information. All
registers are read/write unless otherwise indicated, and are set to default values
following a software, power, and pin reset. A software reset is always performed
at power-up, and when register bit SRESET (1B[7]) is set to 1.
