Programming error causing a CPU fault
Access to a prohibited address:
- *pBuf parameter error,
- *pBuf+Requestno outside authorised area,
- *No_read parameter error.
Programming in C Language
The time, date and size are in INTEL format, i.e. the MSBs and LSBs are reversed with respect to the MOTOROLA
format.
In the MOTOROLA format, these bits are as follows:
