96 KByte Flash Module (S12FTMRG96K1V1)
28.4.4.3 Valid Flash Module Commands
Table 28-27 present the valid Flash commands, as enabled by the combination of the functional MCU
mode (Normal SingleChip NS, Special Singlechip SS) with the MCU security state (Unsecured, Secured).
Special Singlechip mode is selected by input mmc_ss_mode_ts2 asserted. MCU Secured state is selected
by input mmc_secure input asserted.
