URD.exe - Program used to read back responses from a target device. If a DSP-type device
is selected and the INTREQ pin is not low when URD.exe is executed, the program will wait
until INTREQ drops. Press the ‘Enter’ key to exit the read wait loop.
Usage: urd [-dZZZZ..] [-mY] [-pXXX] [-v] [-h]
-d = device
ZZZZ = device designator, eg dspab, dspc, 8415a, etc.
-m = communication mode
Y = mode designator (i=I2C, s=SPI*, m=MOT, n=INT)
-p = parallel port address
XXX = address in hex (278, 378* or 3bc)
-v = enable verbose mode
-h = this message
* = default value
EXAMPLE: urd -d4940c -p378
Notes: If the associated INTREQ pin is not low when URD is executed, the program will wait
until INTREQ drops for DSP devices ONLY. Press the ‘Enter’ key to exit the program in this case.
URST.exe - Program used to perform hard reset or soft reset on the target device.
Usage:
urst [-dZZZZ..] [-mY] [-s] [-pXXX] [-v] [-h]
-d = device
ZZZZ = device designator, eg dspab, dspc, 8415a
-m = communication mode
Y = mode designator (i = I2C, s = SPI*, n = INTEL, m = MOTOROLA)
-s = Soft Reset
-p = parallel port address
XXX = address in hex (278, 378* or 3bc)
-v = enable verbose mode
-h = this message
* = default value
SetPLD.exe - Program used to read and write PLD registers.
Usage: setpld -r/-w RR [DD]
Where -r is to read from register RR, -w is to write data DD into register RR. RR and DD
are in hex.
