What could be the problem if I'm not able to write this value to this register?
*AT91C_EMAC_TCR = 0x30;
If I take a look in the memory window I don't see this value in this register...
assembly-window shows this code for this c-line:
0x100002E4 E3A00030 MOV R0,#0x00000030 0x100002E8 E2441911 SUB R1,R4,#0x00044000 0x100002EC E5810010 STR R0,[R1,#0x0010]
Looks really good, but it doesn't work... I'm working with the AT91Rm9200 controller from Atmel.
best regards Johannes
What is TCR? A transmit register?
Note that special function registers are not identical to memory cells, i.e. you are not guaranteed to be able to read back what you write.
Some registers can only be read. Some can only be written. Some can be written, but will have some bits replaced with ones or zero when reading back.
