Microprocessor Interface Data bus. See Microprocessor Interface Section. P15 is the MSB.
Microprocessor Interface Address bus. ADD2 is the MSB. See Microprocessor Interface Section.
Microprocessor Interface Write or Data Strobe Signal. When the Microprocessor Interface Mode
Control (µP 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 µP 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.
Microprocessor Interface Read or Read/Write Signal. When the Microprocessor Interface Mode
Control (µP 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 µP 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.
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 µP MODE
is 0, the microprocessor interface consists of separate RD and WR strobes; when µP MODE is 1, the
interface consists of a RD/WR control and a single data strobe. See the Microprocessor Interface
Section.
Microprocessor Interface Chip Select. Active low. This pin has the same timing requirements as the
address pins.
