10.6.8 Register Description
SPI CONTROL REGISTER (SPICR)
Read/Write
Reset Value: 0000 xxxx (0xh)
Bit 7 = SPIE Serial Peripheral Interrupt Enable
This bit is set and cleared by software.
0: Interrupt is inhibited
1: An SPI interrupt is generated whenever an End
Bit 6 = SPE Serial Peripheral Output Enable
This bit is set and cleared by software. It is also
cleared by hardware when, in master mode,
SS = 0 (see
(MODF)"). The SPE bit is cleared by reset, so the
SPI peripheral is not initially connected to the ex-
ternal pins.
0: I/O pins free for general purpose I/O
1: SPI I/O pin alternate functions enabled
Bit 5 = SPR2 Divider Enable
This bit is set and cleared by software and is
cleared by reset. It is used with the SPR[1:0] bits to
set the baud rate. Refer to
Mode SCK
0: Divider by 2 enabled
1: Divider by 2 disabled
Note: This bit has no effect in slave mode.
Bit 4 = MSTR Master Mode
This bit is set and cleared by software. It is also
cleared by hardware when, in master mode,
SS = 0 (see
(MODF)").
0: Slave mode
1: Master mode. The function of the SCK pin
SPIE
of Transfer event, Master Mode Fault or Over-
run error occurs (SPIF = 1, MODF = 1 or
OVR = 1 in the SPICSR register)
changes from an input to an output and the func-
tions of the MISO and MOSI pins are reversed.

Bit 3 = CPOL Clock Polarity
This bit is set and cleared by software. This bit de-
termines the idle state of the serial Clock. The
CPOL bit affects both the master and slave
modes.
0: SCK pin has a low level idle state
1: SCK pin has a high level idle state
Note: If CPOL is changed at the communication
byte boundaries, the SPI must be disabled by re-
setting the SPE bit.
Bit 2 = CPHA Clock Phase
This bit is set and cleared by software.
0: The first clock transition is the first data capture
1: The second clock transition is the first capture
Note: The slave must have the same CPOL and
CPHA settings as the master.
Bits 1:0 = SPR[1:0] Serial Clock Frequency
These bits are set and cleared by software. Used
with the SPR2 bit, they select the baud rate of the
SPI serial clock SCK output by the SPI in master
mode.
Note: These 2 bits have no effect in slave mode.
