C6748 LCDK GEL Script PLL1 Configuration

Tsutomu Furuse

Hi.

In C6748_LCDK.gel, there is a PLLCTL.EXTCLKSRC clearing operation for PLL1. But I assume that the EXTCLKSRC register field exists only in PLL0. So I suppose that it is a typo and it's not necessary for the PLL1 initialization. Is my understanding correct?

/* PLLCTL.EXTCLKSRC bit 9 should be left at 0 for Freon */
PLL1_PLLCTL &= ~(0x00000200);

Hello Tsutomu,

Yes, EXTCLKSRC is applicable only for PLL0 and not for PLL1. The bit 9 in PLL1_PLLCTL is reserved and the above sequence is not valid for PLL1 initialization.

Thanks for pointing out this, we would correct this in next release.
