D_RMR D_ch Receive Message Ready
A 64-byte data is available in the D_RFIFO. The frame is not complete yet.
D_RME D_ch Receive Message End
The last part of a frame with length > 32 bytes or a whole frame with length
32 bytes has
been received. The whole frame length is obtained from D_RBCH + D_RBCL registers. The length of data in
the D_RFIFO equals:
data length = RBC4-0 if RBC4-0
0
data length = 32 if RBC4-0 =0
D_XFR D_ch Transmit FIFO Ready
This bit indicates that the transmit FIFO is ready to accept data. Up to 32 bytes of data can be written into the
D_XFIFO.
An D_XFR interrupt is generated in the following cases :
- After an XMS command, when
32 bytes of XFIFO is empty
- After an XMS together with an XME command is issued, when the whole frame has been transmitted
- After an XRST command
-
After hardware reset or software reset
INT1 INT1 Interrupt
If the INT1 bit is set to “1”, this bit indicates that interrupt trigger occurs at INT1 pin.
INT0 INT0 Interrupt
If the INT0 bit is set to “1”, this bit indicates that interrupt trigger occurs at INT0 pin.
D_EXI D_ch Extended Interrupt
This bit indicates that at least one interrupt bit is set in D_EXIR register.
Note
: A read of the ISTA register clears all bits except D_EXI, D_EXI bit is cleared when all bits in D_EXIR
register are cleared.
