Interrupt Status Register (READ)
ISTA
Value after RESET: 00
RME. . .Receive Message End
RPF. . .Receive Pool Full
RSC. . .Receive Status Change (significant in auto-mode only!)
XPR. . .Transmit Pool Ready
TIN. . .Timer Interrupt
ICA … Interrupt of Channel A (Channel B only)
Semiconductor Group
One message up to 32 bytes or the last part of a message greater then 32 bytes has
been received and is now available in the RFIFO. The message is complete!
The actual message length can be determined reading the RBCH, RBCL registers.
Additional information is available in the RSTA register.
A block of 32 bytes of a message is stored in the RFIFO. The message is not yet
completed!
Note: This interrupt is only generated in Interrupt Mode!
A status change (receiver ready/receiver not ready) of the opposite station has been
detected in auto-mode. (i.e. the HSCX has received a RR/RNR supervisory frame
according to the HDLC protocol.) The current status can be read from the STAR
register (RRNR bit).
A data block of up to 32 bytes can be written to the transmit FIFO.
The internal timer and repeat counter has been expired. (See also description of TIMR
register!)
Indicates, that an interrupt is caused by channel A and the interrupt source(s) is (are)
indicated in the ISTA register of channel A (i.e. at least one bit of the ISTA register of
channel A is set).
