(C5h) : Crystal Status Register
(C6h) : Internal Ring Oscillator Control Register
: Crystal oscillator warm-up status.
(C7h) : Internal Ring Oscillator Control Register
This bit is cleared by H/W during executing Power-on reset
or during exiting from the power-down mode.
It is set by H/W after XTAL stabilization.
0 = Internal ring Oscillator is killed.
Don’t clear RINGON bit when XTRG = 0.
[0,0,0] = F
[0,0,1] = F
[0,1,0] = F
[0,1,1] = F
[1,0,0] = F
[1,0,1] = F
[1,1,0] = F
0 = Test Internal ring Oscillator is killed.
Must clear the flag for saving power at STOP mode
