to determine the source of the interrupt and will vector to the reset vector
as a default.
SPE — Serial Peripheral Enable Bit
The SPE bit switches the port B interface such that SDO/PB5 is the serial data output, SDI/PB6 is the
serial data input, and SCK/PB7 is a serial clock input in the slave mode or a serial clock output in the
master mode. The port B DDR and data registers can be manipulated as usual, but these actions will
not affect the transmitted or received data. The SPE bit is readable and writable at any time, but
clearing the SPE bit while a transmission is in progress will 1) abort the transmission, 2) reset the serial
bit counter, and 3) convert port B to a general-purpose I/O port. Reset clears the SPE bit.
1 = Serial peripheral enabled (port B I/O disabled)
0 = Serial peripheral disabled (port B I/O enabled)
LSBF — Least Significant Bit First Bit
The LSBF bit controls the format of the transmitted and received data to be transferred LSB or MSB
first. Reset clears this bit.
1 = LSB transferred first
0 = MSB transferred first
MSTR — Master Mode Select Bit
The MSTR bit configures the serial I/O port for master mode. A transfer is initiated by writing to the
SDR. Also, the SCK pin becomes an output providing a synchronous data clock dependent upon the
divider of the oscillator frequency selected by the SPR0:1 bits. When the device is in master mode, the
SDO and SDI pins do not change function. These pins behave exactly the same in both the master
and slave modes. The MSTR bit is readable and writable at any time regardless of the state of the SPE
bit. Clearing the MSTR bit will abort any transfers that may have been in progress. Reset clears the
MSTR bit, placing the SIOP subsystem in slave mode.
1 = SIOP set up as master, SCK is an output
0 = SIOP set up as slave, SCK is an input
SPIR — Serial Peripheral Interrupt Reset Bit
The SPIR bit is a write-only control to reset the SPIF flag bit in the SSR. Reading the SPIR bit will return
a logic 0.
1 = Reset the SPIF flag bit
0 = No effect
CPHA — Clock Phase Bit
The CPHA bit controls the clock timing and phase in the SIOP. Data is changed on the falling edge of
SCK and data is captured (read) on the rising edge of SCK. This bit is cleared by reset.
1 = SCK is idle low
0 = SCK is idle high
SPR0:1 — Serial Peripheral Clock Rate Select Bits
The SPR0 and SPR1 bits select one of four clock rates given in Table 9-1 to be supplied on the
PB7/SCK pin when the device is configured with the SIOP as a master (MSTR = 1). The fastest rate
is when both SPR0 and SPR1 are set. Both the SPR0 and SPR1 bits are cleared by reset, which
places the SIOP clock selection at the slowest rate.
