ATA6264 [Preliminary]
The overtemperature bits a5, a6 and a7 are latched when overtemperature is detected. These
bits will be reset with the next SPI command, unless overtemperature still exists.
In the case of a reset, bits b4 and b5 are not set to their default state. These bits show the status
before reset so that the microcontroller can detect whether or not the ATA6264 is in power-up
state.
