7 PIN DESCRIPTIONS
7.1 Pin Functional Description
Note that all digital pins are IO pins in JTAG mode. This feature increases the effectiveness of board level ATPG
patterns.
LEGEND: I = input, O = output, Ipu = input with pullup, Oz = output with tri-state, IO = bidirectional pin, IOz = bidirectional pin with tri-state.

Data Bit 2: Bidirectional data bit 2 of the microprocessor interface.
Not driven when CS = 1 or RST = 0.
Data Bit 3: Bidirectional data bit 3 of the microprocessor interface.
Not driven when CS = 1 or RST = 0.
Data Bit 4: Bidirectional data bit 4 of the microprocessor interface.
Not driven when CS = 1 or RST = 0.
Data Bit 5: Bidirectional data bit 5 of the microprocessor interface.
Not driven when CS = 1 or RST = 0.
Data Bit 6: Bidirectional data bit 6 of the microprocessor interface.
Not driven when CS = 1 or RST = 0.
Data Bit 7: Bidirectional data bit 7 of the microprocessor interface.
Most Significant Bit. Not driven when CS = 1 or RST = 0.
Write (Intel Mode): The DS33R11 captures the contents of the
data bus (D0-D7) on the rising edge of WR and writes them to the
addressed register location. CS must be held low during write
operations.
Read Write (Motorola Mode): Used to indicate read or write
operation. RW must be set high for a register read cycle and low for
a register write cycle.
