7.3 SPI Data Register (S0SPDR - 0xE002 0008)
7.4 SPI Clock Counter Register (S0SPCCR - 0xE002 000C)
7.5 SPI Test Control Register (SPTCR - 0xE002 0010)
Table 463: SPI Status Register (S0SPSR - address 0xE002 0004) bit description
This bi-directional data register provides the transmit and receive data for the SPI.
Transmit data is provided to the SPI by writing to this register. Data received by the SPI
can be read from this register. When a master, a write to this register will start a SPI data
transfer. Writes to this register will be blocked from when a data transfer starts to when the
SPIF status bit is set, and the status register has not been read.
Table 464: SPI Data Register (S0SPDR - address 0xE002 0008) bit description
This register controls the frequency of a master’s SCK. The register indicates the number
of SPI peripheral clock cycles that make up an SPI clock.
In Master mode, this register must be an even number greater than or equal to 8.
Violations of this can result in unpredictable behavior. The SPI0 SCK rate may be
calculated as: PCLK_SPI / SPCCR0 value. The SPI peripheral clock is determined by the
PCLKSEL0 register contents for PCLK_SPI.
In Slave mode, the SPI clock rate provided by the master must not exceed 1/8 of the SPI
peripheral clock selected in
relevant.
Table 465: SPI Clock Counter Register (S0SPCCR - address 0xE002 000C) bit description
Note that the bits in this register are intended for functional verification only. This register
should not be used for normal operation.

Description
Read overrun. When 1, this bit indicates that a read overrun has
occurred. This bit is cleared by reading this register.
Write collision. When 1, this bit indicates that a write collision has
occurred. This bit is cleared by reading this register, then
accessing the SPI data register.
SPI transfer complete flag. When 1, this bit indicates when a SPI
data transfer is complete. When a master, this bit is set at the
end of the last cycle of the transfer. When a slave, this bit is set
on the last data sampling edge of the SCK. This bit is cleared by
first reading this register, then accessing the SPI data register.
Note: this is not the SPI interrupt flag. This flag is found in the
SPINT register.
Description
SPI Bi-directional data port.
If bit 2 of the SPCR is 1 and bits 11:8 are other than 1000, some
or all of these bits contain the additional transmit and receive
bits. When less than 16 bits are selected, the more significant
among these bits read as zeroes.
Description
