The value of A0 (LSB) is loaded from pin ADR/PSW during reset (including power-on reset). If pin
ADR/PSW = HIGH, bit A0 = 1; otherwise bit A0 = 0.
One-byte write to the specified register address.
Multi-byte write to N consecutive registers, starting from the specified start address. N
defines the number of registers to write. If N = 1, only the start register is written.
