Negative voltage range. This bit switches between the low and high voltage range of the nega-
tive charge pump in programming and erasing the CMF Flash module when GDB = 0b1. This
bit is writeable when HVS = 0b0.
0 = High Range (more negative)
1 = Low Range
Program amplitude/width modulation select. The PAWS bits, in conjunction with the NVR and
GDB bits can be used to select the programming voltage applied to the drain or gate of the EE-
PROM bitcell. These bits should be left set to 0b000, unless advised by Motorola. For informa-
tion about PAWS programming modes, see
Reserved
This bit is reserved for Motorola factory testing and should always be programmed to 0b0.
0 = Normal Operation
1 = Factory test mode use only. This setting could disturb contents of flash.
Gate/drain bias select. This bit works in conjunction with the PAWS bits to select between pos-
itive and negative ramped voltages for programing and erasing. This bit is writeable when SES
= 0b0.
0 = Positive voltage ramp selected on the bitcell drain.
1 = Negative voltage ramp selected on the bitcell gate.
