RW BURST

Enable burst mode

Disabled

Burst mode is disabled (normal operation)

Enabled

Burst mode is enabled. SAADC takes 2^OVERSAMPLE

number of samples as fast as it can, and sends the average

to Data RAM.

6.17.11.39 OVERSAMPLE

Address offset: 0x5F4

Oversampling configuration. OVERSAMPLE should not be combined with SCAN. The RESOLUTION is

applied before averaging, thus for high OVERSAMPLE a higher RESOLUTION should be used.
