W742E/C811

Bit 2, Bit 1, Bit 0 RAM page bits:

000 = Page 0 (00H - 0FH)

001 = Page 1 (10H - 1FH)

010 = Page 2 (20H - 2FH)

011 = Page 3 (30H - 3FH)

100 = Page 4 (40H - 4FH)

101 = Page 5 (50H - 5FH)

110 = Page 6 (60H - 6FH)

111 = Page 7 (70H - 7FH)

5.4.3 WR Page Register (WRP)

The WR page register is organized as a 4-bit binary register. The bit descriptions are as follows:

3

WRP R/W R/W R/W R/W

Note: R/W means read/write available.

Bit 3, Bit 2, Bit 1, Bit 0 Working registers page bits:

0000 = WR Page 0 (00H - 0FH)

0001 = WR Page 1 (10H - 1FH)

0010 = WR Page 2 (20H - 2FH)

0011 = WR Page 3 (30H - 3FH)

0100 = WR Page 4 (40H - 4FH)

0101 = WR Page 5 (50H - 5FH)

0110 = WR Page 6 (60H - 6FH)

0111 = WR Page 7 (70H - 7FH)

1000 = WR Page 8 (80H - 8FH)

1001 = WR Page 9 (90H - 9FH)

1010 = WR Page A (A0H - AFH)

1011 = WR Page B (B0H - BFH)

1100 = WR Page C (C0H - CFH)

1101 = WR Page D (D0H - DFH)

1110 = WR Page E (E0H - EFH)
