Address [12:0]. This bus selects a specific register in the DS26528 during
read/write access. A12 is the MSB and A0 is the LSB.
Data [7:0]. This 8-bit, bidirectional data bus is used for read/write access of the
DS26528 information and control registers. D7 is the MSB and D0 is the LSB.
Chip-Select Bar. This active-low signal is used to qualify register read/write
accesses. The RDB/DSB and WRB signals are qualified with CSB.
Read-Data Bar/Data-Strobe Bar. This active-low signal along with CSB qualifies
read access to one of the DS26528 registers. The DS26528 drives the data bus
with the contents of the addressed register while RDB and CSB are low.
Write-Read Bar/Read-Write Bar. This active-low signal along with CSB qualifies
write access to one of the DS26528 registers. Data at D[7:0] is written into the
addressed register at the rising edge of WRB while CSB is low.
Interrupt Bar. This active-low, open-drain output is asserted when an unmasked
interrupt event is detected. INTB will be deasserted when all interrupts have been
acknowledged and serviced. Extensive mask bits are provided at the global level,
framer, LIU, and BERT level.
Bus Type Select. Set high to select Motorola bus timing, low to select Intel bus
timing. This pin controls the function of the RDB/DSB and WRB pins.
