PLL
- Main clock F_OSC=14,7MHz @ Olimex LPC-P2106) [limits: 10 MHz to 25 MHz]
- System should run at max. Frequency (60MHz) [limit: max 60 MHz]
- Choose multiplier M=4
so cclk = M * F_OSC= 4 * 14745000Hz = 58980000 Hz
- MSEL-Bit in PLLCFG (bits 0-4) MSEL = M-1
- F_CCO must be inbetween the limits 156 MHz to 320 MHz
datasheet: F_CCO = F_OSC * M * 2 * P
- choose devider P=2 => F_CCO = 14745000Hz * 4 * 2 * 2
= 235920000 ~=236 MHz
- PSEL0 (Bit5 in PLLCFG) = 1, PSEL1 (Bit6) = 0 (0b01)
