6.3 - ADDRESSING SPACE
6.3.1 - General Mapping
STV9432 registers, RAM and ROM are mapped in a 32K address space.
The mapping is:
0000
03FF
0400
07FF
0800
3FFF
4000
403F
4040
7FFF
1024 bytes RAM
Empty Space
Character Generator ROM
Internal Registers
Empty Space
Descriptors and character codes
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.
