This value controls the SPI clock frequency. Pass 0-65535. Default=0 corresponds to 65536 internally which results in ~800 kHz. 65500 = ~100 kHz, 65100 = ~10 kHz, 61100 = ~1 kHz, 21000 = ~100 Hz, and 1 = ~67 Hz. Avoid setting too low such that the entire transaction lasts longer than the 250 millisecond timeout of the internal watchdog timer.

• Data type: UINT16  (type index = 0)
