Freescale Semiconductor
buclk_enable = (STBUC | LOC) and LME lock indicates loss of lock status
bit (LOCS) for all cases and loss of clock sticky bit (LOCSS) when state 3
is active. When buclk_enable is changed, the chip asserts HRESET to
switch the system clock to BUCLK or PLL.
At PORESET negation, if the PLL is not locked, the loss-of-clock sticky bit
(LOCSS) is asserted, and the chip should operate with BUCLK.
