All SDCC -
I have a question about an idata data type on an 8051
architecture:
For example:
static volatile unsigned char idata rxbuf[32]; //
Uart receive buffer
On a
8-bit architecture where ISRs are used... do I need to protect accesses to
this array to ensure that data is not corrupted? Using the critical { }
compiler directive for instance.
Or
does interaction with this buffer not require this
protection?
Thanks
in advance for your help on this.
