SSOE — Slave Select Output Enable
LSBFE — LSB First (Shifter Direction)
13.4.2
This read/write register is used to control optional features of the SPI system. Bits 7, 6, 5, and 2 are not
implemented and always read 0.
MODFEN — Master Mode-Fault Function Enable
Freescale Semiconductor
This bit is used in combination with the mode fault enable (MODFEN) bit in SPCR2 and the
master/slave (MSTR) control bit to determine the function of the SS1 pin as shown in
When the SPI is configured for slave mode, this bit has no meaning or effect. (The SS1 pin is the slave
select input.) In master mode, this bit determines how the SS1 pin is used (refer to
details).
1 = SPI serial data transfers start with least significant bit.
0 = SPI serial data transfers start with most significant bit.
1 = Mode fault function enabled, master SS1 pin acts as the mode fault input or the slave select
0 = Mode fault function disabled, master SS1 pin reverts to general-purpose I/O not controlled by
output.
