  • Port 0xEF = GPIO_B Config
  • Port 0xF0 = GPIO_B Output Enable
  • Port 0xF1 = GPIO_B Input Enable
  • Port 0xF2 = GPIO_B Data
  • Port 0xF8 = GPIO_E Output Enable
  • Port 0xF9 = GPIO_E Input Enable
  • Port 0xFA = GPIO_E Data


The AK1022 and CTW500 chips seem to be the same as the ATJ2093 chips.
