2.4 Input/Output Registers
The first 32 addresses of the memory space, $0000–$001F, contain the
I/O Registers section as summarized in Figure 2-2.
One I/O register is located outside the 32-byte I/O section, which is the
computer operating properly (COP) register mapped at $1FF0.
The assignment of each control, status, and data bit in the I/O register
space from $0000–$001F is given in Figure 2-3 and Figure 2-4.
