RWTBL46: Read and Write Tables 04h, 06h
0 = (Default) Read and write access for PW2 only.
1 = Read and write access for both PW1 and PW2.
RTBL1C: Read Table 01h or Table 05h, Registers F8h –FFh. Table address is dependent on MASK
bit (Table 02h, Register 89h).
0 = (Default) Read access for PW2 only.
1 = Read access for PW1 and PW2.
RTBL2: Read Table 02h except for PW1 value locations (Table 02h, Registers B0h –B3h)
0 = (Default) Read access for PW2 only.
1 = Read access for PW1 and PW2.
RTBL1A: Read Table 01h, Registers 80h –BFh
0 = (Default) Read access for PW2 only.
1 = Read access for PW1 and PW2.
RTBL1B: Read Table 01h, Registers C0h –F7h
0 = (Default) Read access for PW2 only.
1 = Read access for PW1 and PW2.
WPW1: Write Register PW1 (Table 02h, Registers B0h –B3h). For security purposes these registers
are not readable.
0 = (Default) Write access for PW2 only.
1 = Write access for PW1 and PW2.
WAUXAU: Write Auxiliary Memory, Registers 00h –7Fh. All users can read this area.
0 = Write access for PW2 only.
1 = (Default) Write access for user, PW1 and PW2.
WAUXBU: Write Auxiliary Memory, Registers 80h –FFh
0 = Read and write access for PW2 only.
1 = (Default) Read and write access for user, PW1 and PW2.
