3.14 Flash.1: Operating speed out of on-chip flash is restricted
Introduction:
The operating speed of this device out of internal flash/SRAM is specified at 72 MHz.
Problem:
Code execution from internal flash is restricted depending upon the device revision:
1. Rev ‘A’ devices: Code execution from internal flash is restricted to a maximum of
60 MHz.
For example, use a PLL output frequency of F
CCO
= 360 MHz and divide it by 6
(CCLKSEL = 5) to generate 60 MHz CPU clock (do not use even values for CCLKSEL).
2. Rev ‘-’ devices: Code execution from internal flash is restricted to a maximum of
60 MHz also.
However, this device revision has one more restriction in terms of the PLL output
frequency (F
CCO
- Please refer to PLL.1 above). F
CCO
is limited to 290 MHz.
Considering the same example in PLL.1 (Input crystal-12 MHz, N = 1, M = 12):
F
CCO
= 288 MHz
The CPU Clock Configuration register (located at 0xE01F C104) can then be used to
divide this frequency by 6 (CCLKSEL = 5) to achieve 48 MHz. Since this register only
accepts odd values for CCLKSEL, a division by 5 (CCLKSEL = 4) is not a valid option.
In both the above revisions, code can still execute out of SRAM at up to 72 MHz.
Work-around:
None.
