value in two consecutive frames. This is effected by the microprocessor writing the MR control bit MRC to 0. An aborted
transmission is indicated by a MAB (Monitor Channel Data Abort) interrupt status at the transmitter.
7.9 PCI/MP Interface Circuit
7.9.1 PCI Slave Mode And Configuration Serial EEPROM
Management 1.1. All the signals are 5V, 33 MHz compatible. A single function, type 00h configuration header is implemented
for control of the internal ISDN device and external peripheral device(s). Memory mode and/or IO mode can be used for W6692's
register access.
equals FFFFH, a EEPROM empty condition is assumed and chip's internal default configuration data is used, otherwise, the
configuration data stored in serial EEPROM is used. The default configuration data is as follows:
FIG.7.9 SERIAL EEPROM DATA LAYOUT
After power on reset, W6692 starts to read configuration data from serial EEPROM. The first word read is Vendor ID, if it
During a transmission process, it is possible for the receiver to ask a transmission to be aborted by sending an inactive MR bit
W6692 implements slave (target) mode function which meets PCI local bus specification revision 2.2 and PCI Power
A 9346/93C46 type serial EEPROM is used for configuration data storage. The EEPORM's data layout is as follows :
