44 * Implementation Notes
46 * The persistent memories in the Kinetis chip families K10 through
47 * K70 are all manipulated with the Flash Memory Module. Some
48 * variants call this module the FTFE, others call it the FTFL. To
49 * indicate that both are considered here, we use FTFX.
51 * Within the module, according to the chip variant, the persistent
52 * memory is divided into what Freescale terms Program Flash, FlexNVM,
53 * and FlexRAM. All chip variants have Program Flash. Some chip
54 * variants also have FlexNVM and FlexRAM, which always appear
57 * A given Kinetis chip may have 1, 2 or 4 blocks of flash. Here we map
58 * each block to a separate bank. Each block size varies by chip and
59 * may be determined by the read-only SIM_FCFG1 register. The sector
60 * size within each bank/block varies by chip, and may be 1, 2 or 4k.
61 * The sector size may be different for flash and FlexNVM.
63 * The first half of the flash (1 or 2 blocks) is always Program Flash
64 * and always starts at address 0x00000000. The "PFLSH" flag, bit 23
65 * of the read-only SIM_FCFG2 register, determines whether the second
66 * half of the flash is also Program Flash or FlexNVM+FlexRAM. When
67 * PFLSH is set, the second from the first half. When PFLSH is clear,
68 * the second half of flash is FlexNVM and always starts at address
69 * 0x10000000. FlexRAM, which is also present when PFLSH is clear,
70 * always starts at address 0x14000000.
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 sector size.
