C Controller Module Dedicated Functions (for ISR)
The following table shows details on the C Controller module dedicated functions (for ISR).
CCPU_FromBuf_ISR
Reads data from the buffer memory of a MELIPC.
Format
short CCPU_FromBuf_ISR(unsigned short usIoNo, unsigned long ulOffset, unsigned long ulSize, unsigned short*
pusDataBuf)
Argument
Argument
usIoNo
ulOffset
ulSize
pusDataBuf
Description
Reads data of the data size (ulSize) from an address moved by the amount of the offset (ulOffset) from the start of the buffer
memory, and then stores it in the data storage destination (pusDataBuf).
Do not execute this function in a routine other than an interrupt routine.
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 read data as a multiple of 2.
Assure a read data area of the read word count.
Do not specify nonexistent CPU buffer memory.
Do not specify nonexistent buffer memory.
Return value
Return value
0(0000H)
-28158(9202H)
