NOTE:
NVR — Negative Voltage Range Select Bit
PAWS[2:0] — Pulse Amplitude/Width Select Field
The program pulse time is equal to the value selected by the pulse width
timing control. When SES = 1, write to SCLKR[2:0], CLKPE[1:0], and
CLKPM[6:0] only when PAWS[2] = 1. Do not write to PAWS[2:0] during
high-voltage operations.
RSVD6 — Reserved
The read-always NVR bit modulates the negative pump output to
select the negative voltage range in program and erase modes as
shown in
no effect when the GDB bit is clear.
The read-always PAWS[2:0] field selects the pulse drain amplitude
and width for program or erase operations. PAWS[2:0] is writable
when the HVS bit is clear. PAWS[2] must be set for all program and
erase operations. If GDB = 1, the gate/source voltage applied during
program/erase is determined by PAWS[1:0] and NVR and shown in
Table
