THZ: Transmit High-Z
A high level on this pin puts all the TTIPn/TRINGn pins into high impedance state.
THZ is a Schmitt-trigger input.
INT: Interrupt (Active Low)
This is the open drain, active low interrupt output. This pin will stay low until all the active unmasked interrupt indica-
tion bits are cleared.
REFR:
This pin should be connected to ground via an external 10K resistor.
CS: Chip Select (Active Low)
This pin must be asserted low to enable the microprocessor interface. The signal must be asserted high at least once
after power up to clear the internal test modes. A transition from high to low must occur on this pin for each Read/
Write operation and can not return to high until the operation is completed.
CS is a Schmitt-trigger input.
A[10:0]: Address Bus
In parallel mode, the signals on these pins select the register for the microprocessor to access.
In SPI mode, these pins should be connected to ground.
A[10:0] are Schmitt-trigger inputs.
D[7:0]: Bi-directional Data Bus
In parallel mode, the signals on these pins are the data for Read / Write operation.
In SPI mode, the D[7:1] pins should be connected to the ground through a 10 K resistor.
D[7:0] are Schmitt-trigger inputs/outputs.
SDO: Serial Data Output
In SPI mode, the data is serially output on this pin.
MPM: Micro Controller Mode
In parallel mode, set this pin low for Motorola mode or high for Intel mode.
In SPI mode, set this pin to a fixed level (high or low). This pin is useless in SPI mode.
MPM is a Schmitt-trigger input.
RW: Read / Write Select
In parallel Motorola mode, this pin is active high for read operation and active low for write operation.
WR: Write Strobe (Active Low)
In parallel Intel mode, this pin is active low for write operation.
SDI: Serial Data Input
In SPI mode, the address/control and/or data are serially input on this pin.
RW / WR / SDI is a Schmitt-trigger input.
