Product data sheet
6.18.1 Crystal oscillator
6.18.2 PLL
6.18.3 Reset and wake-up timer
6.18 System control
On-chip integrated oscillator operates with external crystal in range of 1 MHz to 30 MHz
and with external oscillator up to 50 MHz. The oscillator output frequency is called f
the ARM processor clock frequency is referred to as CCLK for purposes of rate equations,
etc. f
Section 6.18.2 “PLL”
The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input
frequency is multiplied up into the range of 10 MHz to 60 MHz with a Current Controlled
Oscillator (CCO). The multiplier can be an integer value from 1 to 32 (in practice, the
multiplier value cannot be higher than 6 on this family of microcontrollers due to the upper
frequency limit of the CPU). The CCO operates in the range of 156 MHz to 320 MHz, so
there is an additional divider in the loop to keep the CCO within its frequency range while
the PLL is providing the desired output frequency. The output divider may be set to divide
by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2,
it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and
bypassed following a chip reset and may be enabled by software. The program must
configure and activate the PLL, wait for the PLL to Lock, then connect to the PLL as a
clock source. The PLL settling time is 100 μs.
Reset has two sources on the LPC2131/32/34/36/38: the RESET pin and watchdog reset.
The RESET pin is a Schmitt trigger input pin with an additional glitch filter. Assertion of
chip reset by any source starts the wake-up timer (see wake-up timer description below),
causing the internal chip reset to remain asserted until the external reset is de-asserted,
the oscillator is running, a fixed number of clocks have passed, and the on-chip flash
controller has completed its initialization.
When the internal reset is removed, the processor begins executing at address 0, which is
the reset vector. At that point, all of the processor and peripheral registers have been
initialized to predetermined values.
The wake-up timer ensures that the oscillator and other analog functions required for chip
operation are fully functional before the processor is allowed to execute instructions. This
is important at power on, all types of reset, and whenever any of the aforementioned
functions are turned off for any reason. Since the oscillator and other functions are turned
off during Power-down mode, any wake-up of the processor from Power-down mode
makes use of the wake-up timer.

Match register updates are synchronized with pulse outputs to prevent generation of
erroneous pulses. Software must ‘release’ new match values before they can become
effective.
May be used as a standard timer if the PWM mode is not enabled.
