Bit Address
0xEF to 0xEE
0xED
Mnemonic
Reserved
INTMOD
Default

0
Description
Reserved.
SPI interrupt mode.
INTMOD
0
1
Result
SPI interrupt is set when the SPI Rx buffer is full
SPI interrupt is set when the SPI Tx buffer is empty
4
0xEC
AUTO_SS
1
SS output control (see Figure 112).
AUTO_SS
0
1
Result
The SS pin is held low while this bit is cleared, allowing 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
3
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.
2
0xEA
RxOFW
0
Receive buffer overflow write enable.
RxOFW
0
1
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

Result (f CORE = 4.096 MHz)
f CORE /8 = 512 kHz
f CORE /16 = 256 kHz
f CORE /32 = 128 kHz
f CORE /64 = 64 kHz
