|
* Implementation Notes
|
|
*
|
|
* The persistent memories in the Kinetis chip families K10 through
|
|
* K70 are all manipulated with the Flash Memory Module. Some
|
|
* variants call this module the FTFE, others call it the FTFL. To
|
|
* indicate that both are considered here, we use FTFX.
|
|
*
|
|
* Within the module, according to the chip variant, the persistent
|
|
* memory is divided into what Freescale terms Program Flash, FlexNVM,
|
|
* and FlexRAM. All chip variants have Program Flash. Some chip
|
|
* variants also have FlexNVM and FlexRAM, which always appear
|
|
* together.
|
|
*
|
|
* A given Kinetis chip may have 2 or 4 blocks of flash. Here we map
|
|
* each block to a separate bank. Each block size varies by chip and
|
|
* may be determined by the read-only SIM_FCFG1 register. The sector
|
|
* size within each bank/block varies by the chip granularity as
|
|
* described below.
|
|
*
|
|
* Kinetis offers four different of flash granularities applicable
|
|
* across the chip families. The granularity is apparently reflected
|
|
* by at least the reference manual suffix. For example, for chip
|
|
* MK60FN1M0VLQ12, reference manual K60P144M150SF3RM ends in "SF3RM",
|
|
* where the "3" indicates there are four flash blocks with 4kiB
|
|
* sectors. All possible granularities are indicated below.
|
|
*
|
|
* The first half of the flash (1 or 2 blocks, depending on the
|
|
* granularity) is always Program Flash and always starts at address
|
|
* 0x00000000. The "PFLSH" flag, bit 23 of the read-only SIM_FCFG2
|
|
* register, determines whether the second half of the flash is also
|
|
* Program Flash or FlexNVM+FlexRAM. When PFLSH is set, the second
|
|
* half of flash is Program Flash and is contiguous in the memory map
|
|
* from the first half. When PFLSH is clear, the second half of flash
|
|
* is FlexNVM and always starts at address 0x10000000. FlexRAM, which
|
|
* is also present when PFLSH is clear, always starts at address
|
|
* 0x14000000.
|
|
*
|
|
* The Flash Memory Module provides a register set where flash
|
|
* commands are loaded to perform flash operations like erase and
|
|
* program. Different commands are available depending on whether
|
|
* Program Flash or FlexNVM/FlexRAM is being manipulated. Although
|
|
* the commands used are quite consistent between flash blocks, the
|
|
* parameters they accept differ according to the flash granularity.
|
|
* Some Kinetis chips have different granularity between Program Flash
|
|
* and FlexNVM/FlexRAM, so flash command arguments may differ between
|
|
* blocks in the same chip.
|
|
*
|
|
* Although not documented as such by Freescale, it appears that bits
|
|
* 8:7 of the read-only SIM_SDID register reflect the granularity
|
|
* settings 0..3, so sector sizes and block counts are applicable
|
|
* according to the following table.
