EEPROM SIZE = 0 : Test mode.
EEPROM SIZE = 1 : Normal operation. (Default)
MPD_SET = 0 : MPWDN pin active high.
MPD_SET = 1 : MPWDN pin active low.
PPD_SET = 0 : PPWDN pin active high.
PPD_SET = 1 : PPWDN pin active low.
TEST = 0 : Test mode.
TEST = 1 : Normal operation. (Default)
PCMCIA Fast Ethernet MAC Controller
CMOS Local Clock : A 25Mhz clock, +/- 100 ppm, 40%-60% duty
cycle.
Crystal Oscillator Input : A 25Mhz crystal, +/- 25 ppm can be
connected across XTALIN and XTALOUT.
Crystal Oscillator Output : A 25Mhz crystal, +/- 25 ppm can be
connected across XTALIN and XTALOUT. If a single-ended external
clock (LCLK) is connected to XTALIN, the crystal output pin should
be left floating.
Clock Output 25MHz : This clock is source from LCLK/XTALIN.
Phy Power Down : This pin connects to PHY chip power down mode
control input.
Reset
Reset is active high then place AX88190 into reset mode immediately.
During Falling edge the AX88190 loads the EEPROM data.
Power Supply : +3.3V DC.
Power Supply : +5V DC.
Note : for pure 3.3V single power solution, all the HVDD pin can
connect to +3.3V. Care should be taken that HVDD input power must
be greater or equal ( > = ) than LVDD.
Power Supply : +0V DC or Ground Power.
