Read Data, Differential read signal outputs
Read/Write : read = HIGH, write = LOW
Differential PECL or current mode write data input
In Write mode, a fault is flagged when FLT is high.
In Read Mode, a fault is flagged when FLT is low.
a 5kΩ external resistor must be connected between FLT and VCC.
This pad is used as an input in MDS mode.
a 10kΩ external resistor must be connected between REXT and GND
Serial Enable line. Active High
Serial Clock line. 40 MHz max.
Serial Data line. Bi-directional interface
Controls reader passband or enables the Imr generator depending on the state
of BFCTL bit from Reg.01
Selects the dummy head or performs a system reset depending on the state of
RSTDMY bit from Reg.09
