CHECKING THE STATE OF SPIxIF AGAINST THE SPI CLOCK
C1
C2
//wait for the transmission to complete
//wait for the last clock to finish
//write new data to the buffer
57. Module: SPI (Master Mode)
In Master mode, the SPI Interrupt Flag (SPIxIF)
and the SPIRBF bit (SPIxSTAT<0>) may both
become set one-half clock cycle early, instead of
on the clock edge. This occurs only under the
following circumstances:
• Enhanced Buffer mode is disabled
• the module is configured for serial data output
If the application is using the interrupt flag to deter-
mine when data to be transmitted is written to the
transmit buffer, the data currently in the buffer may
be overwritten.
Work around
Before writing to the SPI buffer, check the SCKx pin
to determine if the last clock edge has passed.
Example 1 (below) demonstrates a method for
doing this. In this example, the RD1 pin functions as
the SPI clock, SCK, which is configured as Idle low.
