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]
are used to select register banks. To select a registers bank, refer to the following
examples and the table below:
R4=0111100 points to the register 0x3C in Bank 2.

D- or PS/2 D+ or PS/2
R5 [0]
D+ line register or PS/2 clock interface register.
R5 [1]
D- line register or PS/2 data interface register.
These two bits are BOTH writable and readable when the MCU is operating under PS/2
mode. But under USB Mode, these two bits cannot be accessed.
R5 [2~7] General purpose registers.
