SPIEN
R/W-0
SPIEN: SPI1 Enable bit
1 = Enables the module and configures SCK1, SDO1, SDI1 and SS1 as serial port pins
0 = Disables the module
Unimplemented: Read as ‘0’
SPISIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
Unimplemented: Read as ‘0’
SPIROV: Receive Overflow Flag bit
1 = A new byte/word was completely received and discarded. The user application has not read the
0 = No overflow has occurred
Unimplemented: Read as ‘0’
SPITBF: SPI1 Transmit Buffer Full Status bit
1 = Transmit has not yet started; SPI1TXB is full
0 = Transmit has started; SPI1TXB is empty
Automatically set in hardware when the CPU writes SPI1BUF location, loading SPI1TXB.
Automatically cleared in hardware when the SPI1 module transfers data from SPI1TXB to SPI1SR.
SPIRBF: SPI1 Receive Buffer Full Status bit
1 = Receive is complete; SPI1RXB is full
0 = Receive is not complete; SPI1RXB is empty
Automatically set in hardware when the SPI1 module transfers data from SPI1SR to SPI1RXB.
Automatically cleared in hardware when the core reads SPI1BUF location, reading SPI1RXB.
Legend:
R = Readable bit
-n = Value at POR
