Register 22h – Global configuration register
Bit7: Write “1” to issue a software reset.
Bit6: Reserved for future use.
Bit5: Low power enable bit.
Bit4: Wake-up enable. If the bit is set, low-power enable bit (Bit-5) can be cleared whenever interrupt
Bit3: Interrupt polarity bit. Refer to Section 7.2.2 for INT pin type implementation.
Bit2: This bit configures the INT signal output as level (“0”; by default) or pulse (“1”) style.
Bit1: GP2 registers mask enable. Set “1” will mask the RST# signal for all GP2 registers. (10h ~ 17h)
Bit0: GP1 registers mask enable. Set “1” will mask the RST# signal for all GP1 registers. (00h ~ 08h)
*Bit1 and Bit0 will not be reset by RST#.
