(B) in [Address] indicates an 8-bit register and (HW) indicates a 16-bit register.
The meaning of the symbols described in [Init.] are listed below:
0, 1: Initial values that are set at initial reset.
(However, the registers for the bus and input/output ports are not initialized at hot start.)
X: Not initialized at initial reset.
–: Not set in the circuit.
