6.16.1 Features
6.17.1 Crystal oscillator
6.17.2 PLL
6.16 Real-time clock
6.17 System control
The Real-Time Clock (RTC) is designed to provide a set of counters to measure time
when normal or idle operating mode is selected. The RTC has been designed to use little
power, making it suitable for battery powered systems where the CPU is not running
continuously (Idle mode).
The on-chip integrated oscillator operates with external crystal in range of 1 MHz to
25 MHz. The oscillator output frequency is called f
frequency is referred to as CCLK for purposes of rate equations, etc. f
the same value unless the PLL is running and connected. Refer to
and
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 70 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, and then connect to the PLL as a
clock source. The PLL settling time is 100 s.
