// Setting the Phased Lock Loop (PLL)
|

// ----------------------------------
|
||||
//
|
||||
// Olimex LPC-P2148 has a 12.0000 mhz crystal
|
||||
//
|
||||
// We'd like the LPC2148 to run at 60 mhz (has to be an even multiple of crystal)
|
||||
//
|
||||
// According to the Philips LPC2148 manual: M = cclk / Fosc where: M = PLL multiplier (bits 0-4 of PLLCFG)
|
||||
// cclk = 60000000 hz
|
||||
// Fosc = 12000000 hz
|
||||
//
|
||||
// Solving: M = 60000000 / 12000000 = 5
|
||||
//
|
||||
// Note: M - 1 must be entered into bits 0-4 of PLLCFG (assign 4 to these bits)
|
||||
//
|
||||
//
|
||||
// The Current Controlled Oscilator (CCO) must operate in the range 156 mhz to 320 mhz
|
||||
//
|
||||
// According to the Philips LPC2148 manual: Fcco = cclk * 2 * P where: Fcco = CCO frequency
|
||||
// cclk = 60000000 hz
|
||||
// P = PLL divisor (bits 5-6 of PLLCFG)
|
||||
//
|
||||
// Solving: Fcco = 60000000 * 2 * P
|
||||
// P = 2 (trial value)
|
||||
// Fcco = 60000000 * 2 * 2
|
||||
// Fcc0 = 240000000 hz (good choice for P since it's within the 156 mhz to 320 mhz range)
|
||||
//
|
||||
// From Table 22 (page 34) of Philips LPC2148 manual P = 2, PLLCFG bits 5-6 = 1 (assign 1 to these bits)
|
||||
//
|
||||
// Finally: PLLCFG = 0 01 00100 = 0x24
|
||||
//
|
||||
// Final note: to load PLLCFG register, we must use the 0xAA followed 0x55 write sequence to the PLLFEED register
|
||||
// this is done in the short function feed() below
|
||||
//
|
