2 The CS1 space is a physical
space of 4 MB. Is uses LA0~LA14
alone and thus LAP AROUND
occurs.
The data bus size is 8 bits.
1 The CS0 space is a physical
of 4 MB. It uses LA0~LA16
alone and thus LAP AROUND
occurs.
In addition, the data bus size is
set to 8 bits using the operation
mode setting terminal of the CPU.
3 The CS2 space is a physical
space of 4 MB. It uses LA0~LA11
alone and thus LAP
AROUND occurs.
The data bus size is 8 bits.
4 The CS3 space is a physical
space of 4 MB. Is uses LA0~LA19
alone and thus LAP AROUND
occurs.
The data bus size of the LAN
controller is fixed to 8 bits.
