56 The active low write strobe (WRB) signal is low

during a D3MX register write access. The D7-

D0 bus contents are clocked into the

addressed register on the rising WRB edge

while CSB is low.

34 The bidirectional data bus (D7-D0) is used

35 during D3MX register read and write accesses.

55 The test register select (TRS) signal

discriminates between normal and test mode

register accesses. TRS is high during test

mode register accesses, and is low during

normal mode register accesses. The TRS input

has an integral pull down resistor.

TRS should be connected to ground for normal

mode register access.

58 The active low reset (RSTB) signal provides an

asynchronous D3MX reset. RSTB is a Schmitt

triggered input with an integral pull up resistor.
