R4 (RAM select register) contains the address of the registers.
R4 [0~5] are used to select registers in 0x00h~0x3Fh. The address 0x00~0x1F is common
space. After 0x1Fh, SRAM is grouped into four banks.
R4 [6,7] are used to select register banks. To select a registers bank, refer to the following
examples and the table below
:
(1) R4=00001100 and R4=01001100 point to the same register 0x0Ch. Since
0x0Ch is in the common space, Bit 6 and Bit 7 are meaningless.
(2) R4=10111100 points to the register 0x3C in Bank 2.
