Hi, Everyone
I need your help.
I used Ethernet flow control on TM4C1294KCPDT.
My initialization code is like this before writing to the EMACFLOWCTL register
while (HWREG(EMAC0_BASE + EMAC_O_FLOWCTL) & 0x0001) {
}
Because TM4C1294KCPDT datasheet says The EMACFLOWCTL register should
not be written to until FCBBPA bit is cleared.
and FCBBPA bit's reset value is 0.
Now CPU sometimes stop this while() statement.
Is it possible FCBBPA bit is not 0 ?
CPU does not write to this register before access
and Can you tell me reason FCBBPA bit is set ?
Best Regards
Hiroyasu
