Address Bus A is a 24-bit bus on the SNES. It is drawn in orange in the colorized jwdonal schematic, and its individual address lines are labeled CA0-CA23.
It is connected to:
- pins 2-17 and 93-100 of the S-CPU
- pins 23-42 of WRAM
- pins 5-17 and 37-48 of the Cartridge Slot
It is 24 bits wide because that is how big the SNES' address space is.
