These bits enable SPIA interrupts.
1 (R/W): Enable interrupts
0 (R/W): Disable interrupts
The following shows the correspondence between the bit and interrupt:
SPIA_nINTE.OEIE bit:
SPIA_nINTE.TENDIE bit: End-of-transmission interrupt
SPIA_nINTE.RBFIE bit:
SPIA_nINTE.TBEIE bit:
SPIA Ch.n Transmit Buffer Empty DMA Request Enable Register
Register name
Bit
SPIA_nTBEDMAEN
15–0
Bits 15–0
TBEDMAEN[15:0]
These bits enable the SPIA to issue a DMA transfer request to the corresponding DMA
channel (Ch.0– Ch.15) when a transmit buffer empty state has occurred.
1 (R/W): Enable DMA transfer request
0 (R/W): Disable DMA transfer request
Each bit corresponds to a DMA controller channel. The high-order bits for the
unimplemented channels are ineffective.
SPIA Ch.n Receive Buffer Full DMA Request Enable Register
Register name
Bit
SPIA_nRBFDMAEN
15–0
Bits 15–0
RBFDMAEN[15:0]
These bits enable the SPIA to issue a DMA transfer request to the corresponding DMA
channel (Ch.0– Ch.15) when a receive buffer full state has occurred.
1 (R/W): Enable DMA transfer request
0 (R/W): Disable DMA transfer request
Each bit corresponds to a DMA controller channel. The high-order bits for the
unimplemented channels are ineffective.
