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

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 DS33R41 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.
Read Data Strobe (Intel Mode). The DS33R41 drives the data bus (D0–
D7) with the contents of the addressed register while RD and CS are both
low.
Data Strobe (Motorola Mode). Used to latch data through the
microprocessor interface. DS must be low during read and write
operations.
