SERIAL HOST INTERFACE:
A serial microprocessor interface is included in the XRT75L04. The interface is generic and is designed to
support the common microprocessors/microcontrollers. The XRT75L04 operates in Host mode when the
HOST/HW pin is tied “High”. The serial interface includes a serial clock (SClk), serial data input (SDI), serial
data output (SDO), chip select (CS) and interrupt output (INT). The serial interface timing is shown in Figure
11.
The active low interrupt output signal (INT pin) indicates alarm conditions like LOS, DMO and FL to the
processor.
When the XRT75L04 is configured in Host mode, the following input pins,TxLEV_n, TAOS_n, RLB_n, LLB_n,
E3_n, STS-1/DS3_n, REQEN_n, JATx/Rx, JA0 and JA1 are disabled and must be connected to ground.
The Table 14 below illustrates the functions of the shared pins in either Host mode or in Hardware mode.
N
OTE
:
While configured in Host mode, the TxON_n input pins will be active if the TxON_n bits in the control register are set
to “1”, and can be used to turn on and off the transmit output drivers. This permits a system designed for
redundancy to quickly switch out a defective line card and switch-in the backup line card.
