Chapter 24 128 KByte Flash Module (S12XFTM128K2V1)
24.4.4
The Flash module is not affected if the MCU enters wait mode. The Flash module can recover the MCU
from wait via the CCIF interrupt (see
24.4.5
If a Flash command is active (CCIF = 0) or an EE-Emulation operation is pending when the MCU requests
stop mode, the current Flash operation will be completed before the CPU is allowed to enter stop mode.
24.5
The Flash module provides security information to the MCU. The Flash security state is defined by the
SEC bits of the FSEC register (see
register using data read from the security byte of the Flash configuration field at global address
0x7F_FF0F.
