Address Bit 2:
Address bit 2 of the microprocessor
interface.
X86ED (Hardware Mode):
When in Hardware Mode,
setting this pin high enables X.86 encapsulation for both
the transmit and receive data. When 0, HDLC
encapsulation is used. The register used to control this
function in Software Mode is LI.TX86EDE.
Address Bit 3:
Address bit 3 of the microprocessor
interface.
Address Bit 4:
Address bit 4 of the microprocessor
interface.
Address Bit 5:
Address bit 5 of the microprocessor
interface.
Address Bit 6:
Address bit 6 of the microprocessor
interface.
Address Bit 7:
Address bit 7 of the microprocessor
interface.
Address Bit 8:
Address bit 8 of the microprocessor
interface.
Address Bit 9:
Address bit 9 of the microprocessor
interface. Most Significant Bit.
Data Bit 0:
Bi-directional data bit 0 of the microprocessor
interface. Least Significant Bit. Not driven when
CS
= 1 or
RST
= 0.
Master Out Slave In (SPI Mode):
Data stream that
provides the instruction and address information to the
external EEPROM when in SPI Master Mode. MOSI is
updated on the rising edge when CKPHA is set high, and
on the falling edge when set low.
Data Bit 1:
Bidirectional data bit 1 of the microprocessor
interface. Not driven when
CS
= 1 or
RST
= 0.
Master In Slave Out (SPI Mode):
Data path from the SPI
EEPROM to the DS33Z11. Must be synchronous with
SPICK. The Serial EEPROM SPI Interface will provide
data to the DS33Z11, MSB first. MISO is sampled on the
falling edge when CKPHA is set high, and on the rising
edge when set low.
