PIC32MX230F128L-I/PF

32-bit Microcontrollers (up to 512 KB Flash and 64 KB SRAM) with Audio/Graphics/Touch (HMI), CAN, USB, and Advanced Analog

Microchip Technology 

PIC32MX1XX/2XX/5XX 64/100-PIN FAMILY

REGISTER 17-1: SPIxCON: SPI CONTROL REGISTER (CONTINUED)

bit 4

DISSDI: Disable SDI bit

1 = SDI pin is not used by the SPI module (pin is controlled by PORT function)

0 = SDI pin is controlled by the SPI module

bit 3-2

STXISEL<1:0>: SPI Transmit Buffer Empty Interrupt Mode bits

11 = Interrupt is generated when the buffer is not full (has one or more empty elements)

10 = Interrupt is generated when the buffer is empty by one-half or more

01 = Interrupt is generated when the buffer is completely empty

00 = Interrupt is generated when the last transfer is shifted out of SPISR and transmit operations are 

complete

bit 1-0

SRXISEL<1:0>: SPI Receive Buffer Full Interrupt Mode bits

11 = Interrupt is generated when the buffer is full

10 = Interrupt is generated when the buffer is full by one-half or more

01 = Interrupt is generated when the buffer is not empty

00 = Interrupt is generated when the last word in the receive buffer is read (i.e., buffer is empty)

4:

When using the 1:1 PBCLK divisor, the user software should not read or write the peripheral’s SFRs in the

SYSCLK cycle immediately following the instruction that clears the module’s ON bit.

This bit can only be written when the ON bit = 0.

This bit is not used in the Framed SPI mode. The user should program this bit to ‘0’ for the Framed SPI

mode (FRMEN = 1).

When AUDEN = 1, the SPI module functions as if the CKP bit is equal to ‘1’, regardless of the actual value

of CKP.
