RZK Board Support Package

The RZK Board Support Package (BSP) provides drivers for EMAC, WLAN, UART, I

SPI, USB and RTC devices. These drivers, with the exception of the USB driver, use the

RZK Device Driver Framework (DDF) that provides a common interface for gaining

access to various devices. The RZK BSP also provides drivers for different Flash devices

that do not use the DDF. These drivers are simple APIs for read/write/erase operations in

the Flash memory. The RZK BSP includes the following features:

•

A DDF to provide a common interface to gain access to many different devices

•

Reentrancy handled within the driver

•

Drivers offer minimum interrupt latency

•

Configurable
