float phase=*(float*)&read_in_unsigned_int
4 Set all bits to 0.
40 Data with varying sizes of unsigned type.
8 Set all to 0
32 The data is returned in unsigned integer form of
flatten float type. To recast the unsigned integer
back to float use:
float temp = *(float*)&read_in_unsigned_int_var
8 zeros
8 Set all bits to 0. Sets up the read-back buffer with
contents of the current device status. Contents
are immediately available for USB read. The
contents occupy effectively the lower two bytes.
In the case of SPI, contents are transferred to the
serial output buffer, so a second query to the
SERIAL_OUT_BUFFER register is required to
transfer its contents and also to clear the output
buffer.
