MICROPROCESSOR INTERFACE
The microprocessor interface can be accessed through a Standard Peripheral Interface (Serial SPI) or
Standard Parallel Microprocessor Interface. By default, the parallel interface is selected. To use the SPI
interface, the SER/PAR pin must be pulled "High".
6.1
SPI Serial Peripheral Interface Block
The serial microprocessor uses a standard 3-pin serial port with CS, SCLK, and SDI for programming the LIU.
Optional pins such as SDO, INT, and RESET allow the ability to read back contents of the registers, monitor
the LIU via an interrupt pin, and reset the LIU to its default configuration by pulling reset "Low" for more than
10
μ
S. A simplified block diagram of the Serial Microprocessor is shown in
Figure 35
.
6.1.1
Serial Timing Information
The serial port requires 24 bits of data applied to the SDI (Serial Data Input) pin. The Serial Microprocessor
samples SDI on the rising edge of SCLK (Serial Clock Input). The data is not latched into the device until all 24
bits of serial data have been sampled. A timing diagram of the Serial Microprocessor is shown in
Figure 36
.
N
OTE
:
For applications without a free running SCLK, a minimum of 1 SCLK pulse must be applied when CS is “High”,
befrore pulling CS “Low”.
