Architecture
(Cont.)
Table 1 is the memory address map of the 80C196 microcontroller, and the addresses of
the I/O devices. Address locations 0000H through 00FFH and 1FFEH through 207FH are
reserved for the microcontroller. The remaining locations can be used for program/data
memory or memory mapped I/O devices. EPROM occupies the first 64K bytes, where
program codes start from 2080H to FFFFH, and a 2K look-up table resides inside the
EPROM from location 1000H to 17FFH. The 2K scratch RAM and I/O starts from 4000H in
the second page.
The address map requires the following PAL equations to be programmed to the decoder
PAL. The IO_CS lines are enabled after ALE goes low.
