3:
For daisy-chained SPI operation; allows the user to ignore all but the last received byte. SSPxOV is still
set when a new byte is received and BF = 1, but hardware continues to write the most recent byte to
SSPxBUF.
This bit has no effect in Slave modes for which Start and Stop condition detection is explicitly listed as
enabled.
The ACKTIM Status bit is active only when the AHEN bit or DHEN bit is set.
ACKTIM: Acknowledge Time Status bit (I
1 = Indicates the I
0 = Not an Acknowledge sequence, cleared on 9
PCIE: Stop Condition Interrupt Enable bit (I
1 = Enable interrupt on detection of Stop condition
0 = Stop detection interrupts are disabled
SCIE: Start Condition Interrupt Enable bit (I
1 = Enable interrupt on detection of Start or Restart conditions
0 = Start detection interrupts are disabled
BOEN: Buffer Overwrite Enable bit
In SPI Slave mode:

In I
SDAHT: SDAx Hold Time Selection bit (I
1 = Minimum of 300 ns hold time on SDAx after the falling edge of SCLx
0 = Minimum of 100 ns hold time on SDAx after the falling edge of SCLx
SBCDE: Slave Mode Bus Collision Detect Enable bit (I
If on the rising edge of SCLx, SDAx is sampled low when the module is outputting a high state, the
BCLxIF bit of the PIR2 register is set, and bus goes idle
1 = Enable slave bus collision interrupts
0 = Slave bus collision interrupts are disabled
AHEN: Address Hold Enable bit (I
1 = Following the 8th falling edge of SCLx for a matching received address byte; CKP bit of the
0 = Address holding is disabled

C Master mode:
C Slave mode:
This bit is ignored.
1 = SSPxBUF updates every time that a new data byte is shifted in ignoring the BF bit
0 = If new byte is received with BF bit of the SSPxSTAT register already set, SSPxOV bit of the
1 = SSPxBUF is updated and ACK is generated for a received address/data byte, ignoring the
0 = SSPxBUF is only updated when SSPxOV is clear
SSPxCON1 register will be cleared and the SCLx will be held low.
PCIE
SSPxCON3: SSPx CONTROL REGISTER 3
SSPxCON1 register is set, and the buffer is not updated
state of the SSPxOV bit only if the BF bit = 0.
W = Writable bit
x = Bit is unknown
