7.3 - ADDRESSING SPACE
7.3.1 - General Mapping
STV9432TAP registers, RAM and ROM are mapped in a 32Kbytes addressing space.
The mapping is the following:
0000
03FF
1024 bytes RAM
Descriptors and character codes
0400
07FF
0800
3FFF
Empty Space
Character Generator ROM
4000
403F
Internal Registers
4040
7FFF
Empty Space
Important Notice: All 16 bits datas are mapped LSB byte at lower address and MSB byte at higher address.
- Example: H1 12 bits register: @4000: 8 LSB bits - @4001: 4 MSB bits.
- Descriptors must also be written to RAM LSB byte first.
