Clock control
3.10.2
Reference clock (RCLK)
The main clock (f
MSTR
) can be divided to operate at a slower frequency reference clock
(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.
3.10.3
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.
3.10.4
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.
3.10.5
Flash memory interface clock (FMICLK)
The FMICLK clock is an internal clock derived from RCLK, defaulting to RCLK frequency at
power up. The clock can be optionally divided by 2. The FMICLK determines the bus
bandwidth between the ARM core and the Flash memory. Typically, codes in the Flash
memory can be fetched one word per FMICLK clock in burst mode. The maximum FMICLK
frequency is 96MHz.
