• Manufacturer Part Number: PSF21150
• Description: IPAC-X ISDN PC ADAPTER CIRCUIT
• Manufacturer: INFINEON [Infineon Technologies AG]

The IPAC-X indicates to the host that a new data block can be read from the RFIFOx by
means of an RPF interrupt (see previous chapter). User data is stored in the RFIFOx and
information about the received frame is available in the RBCLx and RBCHx registers and
the RSTAx bytes which are listed in
