the MSB is executed for G1 and G2 data read from the serial interface by means of the settings of T/3 and G/B bits.
filters such as the gain detection filter, which always output positive values, the sign bit has no meaning. By
performing one-bit shift processing toward the MSB on values read from the serial interface in the PD63711, the
precision of a value that is read is improved by one bit from reading the LSB bit instead of the sign bit.
avoiding losing a sign due to one-bit shift processing toward the MSB, multiply (shift one bit to the right) a value less
than 0.5 in the final output stage multiplier in advance. By doing so, the correct sign value is read.
On data readout from the serial interface using the 14H command, the following one-bit shift processing toward
The aim of one-bit shift processing toward the MSB is to improve the bit precision of values that are read. For
When reading sign output (positive and negative values) as in the case of balance detection, as a procedure for
