The on-chip flash memory is tightly integrated to the CPU, allowing code execution directly from flash through 256-bit-wide prefetch reads, a pipeline buffer and code block cache. 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 wait states for C29 flash and Table 6-7 for HSM flash at different frequencies. The Flash Parameters table lists the flash parameters.
CPUCLK (MHz) | Wait States (FRDCNTL[RWAIT](1)) |
---|---|
150 < CPUCLK ≤ 200 | 3 |
100 < CPUCLK ≤ 150 | 2 |
0 < CPUCLK ≤ 100 | 1 |
HSMCLK (MHz) | Wait States (FRDCNTL[RWAIT])(1) |
---|---|
80 < HSMCLK ≤ 100 | 2 |
0 < HSMCLK ≤ 80 | 1 |
