ISTAB
interrupt service routine and write back the old mask to the mask register.
4.2.4
Value after reset: 00
MASKB
Each interrupt source can be selectively masked by setting the respective bit in MASKB
(bit positions corresponding to ISTAB register). Masked interrupts are not indicated
when reading ISTAB. Instead, they remain internally stored and will be indicated after
the respective MASKB bit is reset.
4.2.3
Value after reset: 00
RME … Receive Message End
One message up to 64 bytes or the last part of a message greater then 64 bytes has
been received and is now available in the RFIFOB. The message is complete! The actual
message length can be determined reading the RBCHB, RBCLB registers. Additional
information is available in the RSTAB register.
RPF … Receive Pool Full
A block of 64 bytes of a message is stored in the RFIFOB. The message is not yet
completed!
Note: This interrupt is only generated in interrupt mode, not in DMA mode.
XPR … Transmit Pool Ready
A data block of up to 64 bytes can be written to the transmit FIFO.
To generate edges at the INT pin it is necessary to mask all interrupts at the end of the
