PIC16F946
FIGURE 14-1:
To enable the serial port, SSPEN bit (SSPCON<5>)
must be set. To reset or reconfigure SPI mode:
• Clear bit SSPEN
• Re-initialize the SSPCON register
• Set SSPEN bit
This configures the SDI, SDO, SCK and SS pins as
serial port pins. For the pins to behave in a serial port
function, they must have their data direction bits (in the
TRISC register) appropriately programmed. This is:
• SDI must have TRISC<7> set
• SDO must have TRISC<4> cleared
• SCK (Master mode) must have TRISC<6>
• SCK (Slave mode) must have TRISC<6> set
• SS must have TRISA<5> set.

control enabled (SSPCON<3:0> = 0100),
the state of the SS pin can affect the state
read back from the TRISC<4> bit. The
peripheral OE signal from the SSP module
into PORTC controls the state that is read
back from the TRISC<4> bit (see
Section 19.4
PIC16F946-I (Industrial), PIC16F946-E
(Extended)” for information on PORTC).
If read-modify-write instructions, such as
BSF, are performed on the TRISC register
while the SS pin is high, this will cause the
TRISC<4> bit to be set, thus disabling the
SDO output.
