To set this bit to 1, set it to 1 immediately after setting it first to 0 w hile the FMR01 bit is set to 1 (CPU rew rite mode
enable) . Do not generate an interrupt betw een setting the bit to 0 and setting it to 1.
This bit is set to 0 by setting the FMR01 bit to 0 (CPU rew rite mode disabled).
When the FMR01 bit is set to 1 (CPU rew rite mode enabled), bits FMR15 and FMR16 can be w ritten to.
To set this bit to 0, set it to 0 immediately after setting it first to 1.
