Chip Select (Active Low): This pin is asserted Low by the microprocessor  
to enable the microprocessor interface - output in EPROM mode only.  
Write (Active Low): This pin is asserted Low by the microprocessor to  
initiate a write cycle. In Motorola mode, WRB = 1 for Read.  
Read (Active Low): This pin is asserted Low by the microprocessor to  
initiate a read cycle.  
Address Latch Enable: This pin becomes the address latch enable from  
the microprocessor. When this pin transitions from High to Low, the  
address bus inputs are latched into the internal registers. ALE = SCLK in  
Serial mode.

Power-On Reset: Master reset. If PORB is forced Low, all internal states  
are reset back to default values.

Ready/Data Acknowledge: This pin is asserted High to indicate the  
device has completed a read or write operation.

Master/Slave Select: sets the state of the Master/Slave selection  
register, Reg. 34, Bit 1.

SONET or SDH Frequency Select: sets the initial power up state (or state  
after a PORB) of the SONET/SDH frequency selection registers, Reg. 34,  
Bit 2 and Reg. 38, Bit 5, Bit 6 and Reg. 64 Bit 4. When set Low, SDH  
rates are selected (2.048 MHz etc.) and when set High, SONET rates  
are selected (1.544 MHz etc.) The register states can be changed after  
power-up by software.
