Definition of the silicon version code:

The <SPI-frame-ID> (ROM address 3EH) provides information about the register width (1,

2, 3 bytes) and the availability of ‘Burst Mode Read’ and watchdog.

BR: Burst-Mode Read (1 = Burst-Mode Read is supported)

WD: Watchdog (1 = available, 0 = not available)

32-bit, 24-bit, 16-bit: width of SPI frame (see table below)
