The on-chip flash memory is tightly integrated to the CPU, allowing code execution directly from flash through 128-bit-wide prefetch reads and a pipeline buffer. Flash performance for sequential code is equal to execution from RAM. Factoring in discontinuities, most applications will run with an efficiency of approximately 80% relative to code executing from RAM.
This device also has an One-Time-Programmable (OTP) sector used for the dual code security module (DCSM), which cannot be erased after it is programmed.
Table 6-6 lists the minimum required flash wait states at different frequencies. The Flash Parameters table lists the flash parameters.
CPUCLK (MHz) | Wait States (FRDCNTL[RWAIT](1)) |
---|---|
160 < CPUCLK ≤ 200 | 4 |
120 < CPUCLK ≤ 160 | 3 |
80 < CPUCLK ≤ 120 | 2 |
0 < CPUCLK ≤ 80 | 1 |
