The CMFR high-voltage control register (CMFRCTL) controls the
program and erase operations of the CMFR.
HVS — High Voltage Status Bit
Figure 9-5. CMFR High-Voltage Control Register (CMFRCTL)
The read-only HVS bit reflects the status of the program/erase pulse.
Writing to HVS has no effect. HVS is set when a pulse is active and
during recovery. While HVS = 1, accesses to the array cause a bus
error, and SES cannot be changed. The pulse becomes active when
the EHV bit is set and is terminated by clearing EHV or by the pulse
width timing control. See
Freescale Semiconductor, Inc.
