Flash Operation In Low-Power Modes; Functional Modes Of Operation; Flash Reads And Ignored Writes - NXP Semiconductors MKL27Z128VFM4 Reference Manual

Some devices also generate a bus error response as a result of a Read Collision Error
event. See the chip configuration information to determine if a bus error response is also
supported.

45.4.3 Flash Operation in Low-Power Modes

45.4.3.1 Wait Mode
When the MCU enters wait mode, the flash memory module is not affected. The flash
memory module can recover the MCU from wait via the command complete interrupt
(see Interrupts).
45.4.3.2 Stop Mode
When the MCU requests stop mode, if a flash command is active (CCIF = 0) the
command execution completes before the MCU is allowed to enter stop mode.
The MCU should never enter stop mode while any flash
command is running (CCIF = 0).
While the MCU is in very-low-power modes (VLPR, VLPW,
VLPS), the flash memory module does not accept flash
commands.

45.4.4 Functional Modes of Operation

The flash memory module has two operating modes: NVM Normal and NVM Special.
The operating mode affects the command set availability (see
Chip Configuration details of this device for how to activate each mode.

45.4.5 Flash Reads and Ignored Writes

The flash memory module requires only the flash address to execute a flash memory
read.
