Write signal to internal register.
Read signal to internal register.
Interrupt signal to microcontroller. "L": An interrupt is
generated.
Chip select signal.
"L": Read, write, and data bus signals become active.
"L" : the internal registers are initialized and the device enters
power down mode.
Address signal to internal register.
