35 * Implementation Notes
37 * The persistent memories in the Kinetis chip families K10 through
38 * K70 are all manipulated with the Flash Memory Module. Some
39 * variants call this module the FTFE, others call it the FTFL. To
40 * indicate that both are considered here, we use FTFX.
42 * Within the module, according to the chip variant, the persistent
43 * memory is divided into what Freescale terms Program Flash, FlexNVM,
44 * and FlexRAM. All chip variants have Program Flash. Some chip
45 * variants also have FlexNVM and FlexRAM, which always appear
48 * A given Kinetis chip may have 2 or 4 blocks of flash. Here we map
49 * each block to a separate bank. Each block size varies by chip and
50 * may be determined by the read-only SIM_FCFG1 register. The sector
51 * size within each bank/block varies by the chip granularity as
54 * Kinetis offers four different of flash granularities applicable
55 * across the chip families. The granularity is apparently reflected
56 * by at least the reference manual suffix. For example, for chip
57 * MK60FN1M0VLQ12, reference manual K60P144M150SF3RM ends in "SF3RM",
58 * where the "3" indicates there are four flash blocks with 4kiB
59 * sectors. All possible granularities are indicated below.
61 * The first half of the flash (1 or 2 blocks, depending on the
62 * granularity) is always Program Flash and always starts at address
63 * 0x00000000. The "PFLSH" flag, bit 23 of the read-only SIM_FCFG2
64 * register, determines whether the second half of the flash is also
65 * Program Flash or FlexNVM+FlexRAM. When PFLSH is set, the second
66 * half of flash is Program Flash and is contiguous in the memory map
67 * from the first half. When PFLSH is clear, the second half of flash
68 * is FlexNVM and always starts at address 0x10000000. FlexRAM, which
69 * is also present when PFLSH is clear, always starts at address
72 * The Flash Memory Module provides a register set where flash
73 * commands are loaded to perform flash operations like erase and
74 * program. Different commands are available depending on whether
75 * Program Flash or FlexNVM/FlexRAM is being manipulated. Although
76 * the commands used are quite consistent between flash blocks, the
77 * parameters they accept differ according to the flash granularity.
78 * Some Kinetis chips have different granularity between Program Flash
79 * and FlexNVM/FlexRAM, so flash command arguments may differ between
80 * blocks in the same chip.
82 * Although not documented as such by Freescale, it appears that bits
83 * 8:7 of the read-only SIM_SDID register reflect the granularity
84 * settings 0..3, so sector sizes and block counts are applicable
85 * according to the following table.
