Limitation point on the use of PLL0
1. If you stop PLL operation during using PLL0, you should execute following setting in
the same order.
LD (PLLCR0),X0XXXXXXB ; Change the clock fPLL to fOSCH
LD (PLLCR1),0XXXXXXXB ; Stop PLL0
X: Don't care
2. If you shift to STOP mode during using PLL, you should execute following setting in the
same order.
LD (SYSCR2), XXXX01XXB ; Set the STOP mode
LD (PLLCR0), X0XXXXXXB ; Change the system clock fPLL to fOSCH
LD (PLLCR1), 0XXXXXXXB ; Stop PLL0
HALT ; Shift to STOP mode
X: Don't care
Examples of settings are below;
(1) Start Up / Change Control
(OK) High frequ ency oscillator operation mode(fOSCH )PLL0 start up
PLL0 use mode (fPLL )
LD (PLLCR1), 1XXXXXXXB ; PLL0 start up / lock up start
LUP: BIT 5,(PLLCR0) ;
JR Z,LUP ; Check for the flag of lock up end
LD (PLLCR0), X1XXXXXXB ; Change the system clock fOSCH to fPLL
X: Don't care
(2) Change / Stop Control
(OK) PLL0 use mode (fPLL ) High frequency osc illator operation mode(fOSCH )
PLL0 Stop
LD (PLLCR0),X0XXXXXXB ; Change the system clock fPLL to fOSCH
LD (PLLCR1),0XXXXXXXB ; Stop PLL0
X: Don't care
(OK) PLL0 use mode (fPLL ) Set the STOP mode
High frequency oscillator operation mode (fOSCH) PLL stop
HALT(High frequency oscillator stop)
LD (SYSCR2),XXXX01XXB ; Set the STOP mode
(This command can be executed before use of PLL0)
LD (PLLCR0),X0XXXXXXB ; Change the system clock fPLL to fOSCH
LD (PLLCR1),0XXXXXXXB ; Stop PLL0
HALT ; Shift to STOP mode
X: Don't care
(NG) PLL0 use mode (fPLL) Set the STOP mode
HALT(High frequency oscillator stop)
LD (SYSCR2),XXXX01XXB ; Set the STOP mode
(This command can be executed before use of PLL0)
HALT ; Shift to STOP mode
X: Don't care
