User Module Datasheet: SPI Master Datasheet SPIM V 1.30 (CY7C639/638/633/602/601xx, CYRF69xx3) | Cypress Semiconductor
User Module Datasheet: SPI Master Datasheet SPIM V 1.30 (CY7C639/638/633/602/601xx, CYRF69xx3)
Features and Overview
Supports Serial Peripheral Interconnect (SPI) Master protocol
Supports SPI clocking modes 0, 1, 2, and 3
Programmable interrupt on SPI-done condition
SPI Slave devices can be independently selected
The SPIM User Module is a Serial Peripheral Interconnect Master. It performs full duplex synchronous 8- bit data transfers. SCLK phase, SCLK polarity, and LSB First can be specified to accommodate most SPI clocking modes. Controlled by user supplied software, you can configure the slave select signal to control one or more SPI Slave devices.
The SPI User Module also supports two wire serial devices such as optical mouse sensors that employ an SDIO/SCK interface.
