17.2.4.10
This Framed SPI mode is enabled by setting bits
MSTEN
(SPIxCON<31>)
(SPIxCON<30>) to ‘1’. Therefore, both the SCKx and
SSx pins will be inputs. The SSx pin will be sampled on
the sample edge of the SPI clock. When SSx is sam-
pled active, high or low depending on bit, FRMPOL
(SPIxCON<29>), data will be transmitted on the next
transmit edge of SCKx. A connection diagram indicat-
ing signal directions for this operating mode is shown in
Figure 17-10.
The SDO pins is an output and the SCK, SDI and SSx
pins are inputs. Setting the control bit, DISSDO
(SPIxCON<12>), disables transmission at the SDO pin
if Receive Only mode of operation is desired.
Refer to Table 17-7.
The SDI pin must be configured to properly sample the
data received from the slave device by configuring the
sample bit, SMP (SPIxCON<9>).
Refer to timing diagram shown in Figure 17-7 to deter-
mine the appropriate settings.
17.2.4.11
The following bits must be configured as shown for the
Slave mode of operation when configuring the
SPIxCON register:
• Enable Slave Mode –
• Enable Framed SPI support –
• Select SSx pin as Frame Slave (input) –

Note 1: In Framed SPI modes, the SSx pin is used to transmit/receive the frame synchronization pulse.
2: Framed SPI modes require the use of all four pins (i.e., using the SSx pin is not optional).
