MX98905B
Data Transfer ports and Reset port are always acces-
sible no matter what the value of NPGEN and PGSEL
is in I/O map design.
2. ENHANCED FEATURE REGISTERS
2.1 HIDDEN COMMAND REGISTER (R/W) (HCMR)
This register controls all the functions provided in
enhanced mode. It can always be accessed by con-
secutive 2 writes to port 278H, followed by 2
consecutive 2 writes to port 378H, i.e., write ports :
278H
278H
378H
378H (when I/O Base not
sure)
After the I/O base is determined (see functional de-
scription), this register can be accessed by one I/O
instruction using the address assignment shown in
provious section.
NOTE:
Don't write this register through Base+0AH/
Base+1AH (I/O/MEM) except it is confirmed that I/O
base does not conflict with other ADD_on card.
