As an option, there are a number of peripherals that do not have to receive a clock sourced
from the CCU. The USB interface can receive an external clock on pin P2.7, TIM timers
TIM0/ TIM1 can receive an external clock on pin P2.4, and timers TIM2/TIM3 on pin P2.5.
Figure 2.
Reference clock (RCLK)
The main clock (f
(RCLK) for the ARM core and all the peripherals. The RCLK provides the divided clock for
the ARM core, and feeds the dividers for the AHB, APB, External Memory Interface, and
FMI units.
AHB clock (HCLK)
The RCLK can be divided by 1, 2 or 4 to generate the AHB clock. The AHB clock is the bus
clock for the AHB bus and all bus transfers are synchronized to this clock. The maximum
HCLK frequency is 96 MHz.
APB clock (PCLK)
The RCLK can be divided by 1, 2, 4 or 8 to generate the APB clock. The APB clock is the
bus clock for the APB bus and all bus transfers are synchronized to this clock. Many of the
peripherals that are connected to the AHB bus also use the PCLK as the source for external
bus data transfers. The maximum PCLK frequency is 48 MHz.
