MICROPROCESSOR INTERFACE
P(15:0)
I/O
Microprocessor Interface Data bus.
See Microprocessor Interface Section
. P15 is the MSB.
ADD(2:0)
I
Microprocessor Interface Address bus. ADD2 is the MSB.
See Microprocessor Interface Section
.
WR
or
DSTRB
I
Microprocessor Interface Write or Data Strobe Signal. When the Microprocessor Interface Mode
Control (
μ
P MODE) is low, data transfers (from P(15:0) to the internal write holding register) occur on
the low to high transition of WR when CE is asserted (low). When the
μ
P MODE control is high this
input functions as a data strobe DSTRB control. In this mode with RD/WR low, data transfers (from
P(15:0) to the internal write holding register) occur on the low to high transition of DSTRB. With
RD/WR high the data from the address specified is placed on P(15:0) when DSTRB is low.
See the
Microprocessor Interface Section
.
RD
or
RD/WR
I
Microprocessor Interface Read or Read/Write Signal. When the Microprocessor Interface Mode
Control (
μ
P MODE) is low, the data from the address specified is placed on P(15:0) when RD is
asserted (low) and CE is asserted (low). When the
μ
P MODE control is high this input functions as
a Read/Write control input. Data is read from P(15:0) when RD/WR high or written to the
appropriate register when low.
See the Microprocessor Interface Section
.
μ
P MODE
I
PULL DOWN
Microprocessor Interface Mode Control. This pin is used to select the Read/Write mode for the
Microprocessor Interface. When 0, RD and WR, when 1, DSTROBE and RD/WR. When
μ
P MODE
is 0, the microprocessor interface consists of separate RD and WR strobes; when
μ
P MODE is 1, the
interface consists of a RD/WR control and a single data strobe.
See the Microprocessor Interface
Section
.
CE
I
Microprocessor Interface Chip Select. Active low. This pin has the same timing requirements as the
address pins.
