CCPU_ToBuf_ISR
Writes data to the buffer memory of a MELIPC.
Format
short CCPU_ToBuf_ISR(unsigned short usIoNo, unsigned long ulOffset, unsigned long ulSize, unsigned short* pusDataBuf)
Argument
Argument
usIoNo
ulOffset
ulSize
pusDataBuf
Description
• Writes data of the data storage destination (pusDataBuf) of the data size (ulSize) to the address moved by the amount of
the offset (ulOffset) from the start of the buffer memory.
• If this function is executed when the operating status of the CPU is not RUN, an error occurs.
• Do not execute this function in a routine other than an interrupt routine.
• If data is written to the same CPU buffer memory (host CPU) from a routine other than the interrupt routine,
the output value may be intermingled, resulting in an invalid value. Manage resources so data is not written
to the same CPU buffer memory (host CPU).
Warning
• If any function to which an invalid argument is specified is executed, an error such as hardware failure (3C02H) may occur
on the MELIPC.
• This function does not check the specified arguments.
Pay attention to the following points when creating a program.
Specify the address for the write data as a multiple of 2.
Do not specify nonexistent CPU buffer memory.
Do not specify nonexistent buffer memory.
