All other ports in range 000h..FFFh are unused (always FFFFh on NDS, or always 0000h on NDS-lite).
Reading from write-only ports (W) often mirrors to data from other ports.
Additionally, there are 69h Baseband Chip Registers (BB), and 0Ch RF Chip Registers (see BB and RF chapters).
And, POWCNT2 and WIFIWAITCNT control power managment and waitstates, DS Power Management

**メモリ
  4000h R/W   W_MACMEM    MAC memory (0x2000 bytes)
  5F60h       Used for something, not included in the rx circular buffer.
              (ssid maybe?)
  5F80h       W_WEPKEY1 (32 bytes)
  5FA0h       W_WEPKEY2 (32 bytes)
  5FC0h       W_WEPKEY3 (32 bytes)
  5FE0h       W_WEPKEY4 (32 bytes)

Unlike all other NDS memory, the Wifi RAM is left uninitialized after boot.

5F80h - W_WEPKEY1 thru W_WEPKEY4 - Wifi WEP keys (R/W)
These WEP key slots store the WEP keys that are used for encryption for 802.11 keys IDs 0-3.

All other ports in range 000h..FFFh are unused (always FFFFh on NDS, or always 0000h on NDS-lite).
Reading from write-only ports (W) often mirrors to data from other ports.
Additionally, there are 69h Baseband Chip Registers (BB), and 0Ch RF Chip Registers (see BB and RF chapters).
And, POWCNT2 and WIFIWAITCNT control power managment and waitstates, DS Power Management

**メモリ
  4000h R/W   W_MACMEM    MAC memory (0x2000 bytes)
  5F60h       Used for something, not included in the rx circular buffer.
              (ssid maybe?)
  5F80h       W_WEPKEY1 (32 bytes)
  5FA0h       W_WEPKEY2 (32 bytes)
  5FC0h       W_WEPKEY3 (32 bytes)
  5FE0h       W_WEPKEY4 (32 bytes)

Unlike all other NDS memory, the Wifi RAM is left uninitialized after boot.

5F80h - W_WEPKEY1 thru W_WEPKEY4 - Wifi WEP keys (R/W)
These WEP key slots store the WEP keys that are used for encryption for 802.11 keys IDs 0-3.
