SPI communication code for the Cypress CY7C63000 or CY7C63001
(Please consult factory for the CY7C63722 or CY7C63723 codes.)
Note: This programming sequence is not covered in Agilent's product warranty. It is only a recommended example when using the
mentioned Cypress microcontrollers. For the latest updates on Cypress microcontrollers, please contact Cypress at email:
usbapps@cypress.com or call (858) 613-7929 (US).
The following code can be used to implement the SPI data communications. See the schematic in Figure 9.

There are possible problems with the SPI port if the microcontroller starts executing
instructionsbefore the ADNS-2051 sensor has powered up. See page 18 for details.
It is assumed that power to the microcontroller is OK if the next instructions can be executed.
These instructions will reset the SPI port of the sensor.
Resync_sensor:
mov A,~(SCLK|SDIO|PD) ; set the SCLK, SDIO and PD lines low
and [port1_wrote], A
mov A, [port1_wrote]
