NAME:
SWRST

POR*:
0
*POR is defined as the first application of power to the device, either VBAT or VCC.
This register is used for factory test. Bits 6:0 are locked and always read as zeros. Writing to bit locations 6:0 has no affect on the
device. If the SWRST bit is set to Logic 1, the device immediately resets all internal logic and registers (except the SRAM) to their
factory-default POR state.
The device reset occurs during the normal acknowledge time slot following the receipt of the data byte carrying that SWRST
instruction; a NACK occurs due to the resetting action (see Figure 8). The I/O master should terminate the I/O string with a nor-
mal STOP instruction (on the 28th SCL clock). The SWRST bit is automatically cleared to logic 0.
