Description
Reserved.
SPI Interrupt Mode.
INTMOD Result
0 SPI interrupt is set when SPI Rx buffer is full.
1 SPI interrupt is set when SPI Tx buffer is empty.
4
0xEC
AUTO_SS
1
Master Mode, SS Output Control (see Figure 95).
AUTO_SS
0
1
Result
The SS pin is held low while this bit is cleared. This allows manual chip select
control using the SS pin.
Single Byte Read or Write. The SS pin goes low during a single byte
transmission and then returns high.
Continuous Transfer. The SS pin goes low during the duration of the
multibyte continuous transfer and then returns high.

0xEB
SS_EN
0
Slave Mode, SS Input Enable.
When this bit is set to Logic 1, the SS pin is defined as the slave select input pin for the SPI
slave interface.

0xEA
RxOFW
0
Receive Buffer Overflow Write Enable.
RxOFW Result

If the SPI2CRx SFR has not been read when a new data byte is received,
the new byte is discarded.
If the SPI2CRx SFR has not been read when a new data byte is received,
the new byte overwrites the old data.

Master Mode, SPI SCLK Frequency.
SPIR[1:0] Result
00 f CORE /8 = 512 kHz (if f CORE = 4.096 MHz).
01 f CORE /16 = 256 kHz (if f CORE = 4.096 MHz).
10 f CORE /32 = 128 kHz (if f CORE = 4.096 MHz).
11 f CORE /64 = 64 kHz (if f CORE = 4.096 MHz).
