CCPU_WriteDevice_ISR
Writes data to internal user devices and internal system devices of a MELIPC.
Format
short CCPU_WriteDevice_ISR(short sDevType, unsigned long ulDevNo, unsigned long ulSize, unsigned short* pusDataBuf)
Argument
Argument Name
sDevType Device type
ulDevNo Start device number
ulSize Data size
pusDataBuf Data storage destination
Description
This function writes data in the data storage destination (pusDataBuf) for the size specified to the data size (ulSize) to a
device after one specified to the device type (sDevType) and the start device number (ulDevNo).
• Do not execute this function in a routine other than an interrupt routine.
• If data is written to the same device from a routine other than an interrupt routine, the output value may be
intermingled, resulting in an invalid value. Manage resources so data is not written to the same device.
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 a device outside of the range.
