Serial Peripheral Data Transfer Flag
Cleared by hardware to indicate data transfer is in progress or has been
approved by a clearing sequence.
Set by hardware to indicate that the data transfer has been completed.
This bit is cleared when reading or writing SPDATA after reading SPSCR.
Reserved
The value read from this bit is indeterminate. Do not set this bit.
Overrun Error Flag
- Set by hardware when a byte is received whereas SPIF is set (the previous
received data is not overwritten).
- Cleared by hardware when reading SPSCR

Description
Clock Polarity
Cleared to have the SCK set to ’0’ in idle state.
Set to have the SCK set to ’1’ in idle state.
Clock Phase
Cleared to have the data sampled when the SCK leaves the idle
state (see CPOL).
Set to have the data sampled when the SCK returns to idle state (see
CPOL).
