Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent interrupt generation.
As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface.
Very simple, very small.
1. This BSP can support 2443EVT0 board.
If you want to use EVT0 BSP, set followings.
In smdk2443\smdk2443.bat file
set BSP_EVT1=1
-> set BSP_EVT1=
In smdk2443\src\inc\bsp_cfg.h file
#define EVT1
-> #define EVT0
2. Default system tick mode is changed. The value is fixed tick.
Fixed tick means that tick interrupt is occurred every 1ms.
Variable tick means that timer interrupt period is changed when power mode is in idle.
For changing to variable tick
In smdk2443\src\inc\bsp_cfg.h file
#define FIXEDTICK
-> #define VARTICK
In smdk2443\src\Common\Timer\Sources file
SOURCES= timer_fixedtick.c watchdog.c
->
SOURCES= timer_vartick.c watchdog.c
The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for
firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The
W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the
contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary
ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4-
bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight
sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the
W78E58B allows the program memory to be programmed and read electronically. Once the code is
confirmed, the user can protect the code for security

Video-DVM is a very cheap DVM that shows how an output as complex as a videocomposite signal can be generated entirely in software: two I/O pins and three resistors are all the hardware required. Connected to any TV set it displays voltages, included max and min peaks, using both giant digits and an analog bar-display . A serial data output for computer data logging is provided, too.
USBHostSlave is a USB 1.1 host and Device IP core.
– Supports full speed (12Mbps) and low speed (1.5Mbps) operation.
– USB Device has four endpoints, each with their own independent FIFO.
– Supports the four types of USB data transfer control, bulk, interrupt, and isochronous
transfers.
– Host can automatically generate SOF packets.
– 8-bit Wishbone slave bus interface.
– FIFO depth configurable via paramters.
QuickSteps books are recipe books for computer users. They answer the
question 揌ow do I...??by providing a quick set of steps to accomplish the
most common tasks with a particular program. The sets of steps are the
central focus of the book. Sidebar QuickSteps provide information on how to
do quickly many small functions or tasks that are in support of the primary
functions. Sidebar QuickFacts supply information that you need to know about
a subject. Notes, Tips, and Cautions augment the steps, but they are presented
in a separate column to not interrupt the fl ow. Brief introductions are present,
but there is minimal narrative otherwise. Many illustrations and fi gures, a
number with callouts, are also included where they support the steps.
