23.3.1 Control
Register
(SPCR)
SPCR is a 32-bit readable/writable register that controls the transfer data of shift timing and
specifies the clock polarity and frequency.

Although the initial value is 0, these bits will be read as
an undefined value. The write value should always be 0.

R/W First Bit Start
Controls the timing relationship between each bit of
transferred data and the serial bit clock.
0: The first bit transmitted from the HSPI module is set
up such that it can be sampled by the receiving
device on the first edge of HSPI_CLK after the
HSPI_CS
pin goes low. Similarly the first received bit
is sampled on the first edge of HSPI_CLK after the
HSPI_CS
pin goes low.
1: The first bit transmitted from the HSPI module is set
up such that it can be sampled by the receiving
device on the second edge of HSPI_CLK after the
HSPI_CS
pin goes low. Similarly the first received bit
is sampled on the second edge of HSPI_CLK after
the
HSPI_CS
pin goes low.

R/W Serial Clock Polarity
0: HSPI_CLK signal is not inverted and so is low when
inactive.
1: HSPI_CLK signal is inverted and so is high when
inactive.
