RESET (5 V tolerant input). The ZL30407 must be reset after power-up in
order to set internal registers into a default state. The internal reset is
performed by forcing RESET pin low for a minimum of 1 Ps after the C20
Master Clock is applied to pin C20i. This operation forces the ZL30407 internal
state machine into a RESET state for a duration of 625 Ps.
Hardware/Software Control (Input). If this pin it tied low, the ZL30407 is
controlled via the microport. If it is tied high, the ZL30407 is controlled via the
control pins MS1, MS2, FCS, RefSel, RefAlign, E3/DS3 and E3DS3/OC3.
Data 0 to Data 3 (5 V tolerant three-state I/O). These ports combined with D4 -
D7 ports form the bi-directional data bus of the microprocessor interface (D0 is
the least significant bit).
Ground
Internal Connection (Input). Connect this pin to ground.
Internal Connection (Input). Connect this pin to ground.
Positive Power Supply
Data 4 to Data 7 (5 V tolerant three-state I/O). These ports combined with D0 -
D3 ports form the bi-directional data bus of the processor interface (D7 is the
most significant bit).
Read/Write Strobe (5 V tolerant input). This input controls the direction of the
data bus D[0-7] during a microprocessor access. When R/W is high, the
parallel processor is reading data from the ZL30407. When low, the parallel
processor is writing data to the ZL30407.
Address 0 (5 V tolerant input). Address input for the microprocessor interface.
A0 is the least significant input.
Internal Connection (Input). Connect this pin to ground.
