3. Address Space
The configuration of the LAN PC card in the MB86967 (in PC card mode) has up to three address spaces (for
common memory, I/O memory, and attribute memory).
Table 5 gives the common memory space, I/O memory space, and attribute memory space of the MB86967.
Table 5 Memory Map for PC Card
Common Memory Space*¹
(E²PROM or FLASH)
I/O Memory Space
• Control registers in LAN controller
(Core of LAN controller)
• LAN card control register
(PC card interface)
• ID number
(E²PROM or FLASH)*²
Attribute Memory Space
• Card attribute data register (CIS)
(E²PROM or FLASH)
• LAN card configuration register
(CCR)
(PC card interface)
Note: Parts in parentheses are the blocks where each item is located.
*1: Common memory space cannot allocated if the E²PROM or flash ROM to be selected is less than 2 Kbytes.
*2: Connecting P97 (ROMAD) to the most significant address bit of ROM allows I/O-reading of the ID number. To
write to this space, both the IOWR and WE pins must be enabled.
