1. Load data command on Bulk erase Data memory, is it load data for program
memory or for data memory?

2. on Begin prog function, "a load command MUST be given before ANY begin
prog command". But on Bulk erase function, the sequence is load data,bulk
erase, begin prog,delay.

I see David Tait's code, he reverses number 1&2, so bulk erase,load data,
begin prog, delay. This is true for begin prog statement.
Is it a bug on prog specs? which is true?

3. Do we need to erase PM&DM after disabling CP? if yes, do we have to
power down first after disabling CP because it executes load cfg (pc set to
0x2000)?
which sequence is right?
Power up, disabling CP, erase PM & DM, power down
or
Power up, disabling CP, power down.
power up, erase PM & DM, power down.
or
power up, erase PM & DM, power down.
Power up, disabling CP, power down.

Thank you very much.
