Class _plla: PLL

Relatives

• Hardware registers: none.
• Logical registers: mul, on, rdy, src, xtpre.

Interface

• Power control

hw|hwa( power, pll,   on
                    | off );

• Configuration

Note

The PLL can not be configured while it is running.

hw|hwa( configure, pll,
 
      [ input,        hsi/2
                    | hse
                    | hse/2, ]
 
      [ multiplier,   2..16 );       // Any value in the range [ 2..16 ]

• Start & stop

hw|hwa( start, pll );

hw|hwa( stop, pll );

• Status

// Wait for the PLL to be locked
//
hw_stat_t(pll) st = hw(stat,pll) ;
while ( ! st.ready ) {}
