I'm using an MC9S08LC60 HCS08 family device. I found the following specification about supply voltage for read operation:
0 < Fbus < 8MHz ---- Vread 1,8 to 3,6V
0 < Fbus < 20MHz ---- Vread 2,08 to 3,6V
Where is the difference? If I use an 8Mhz external resonator to obtain an internal 2Mhz bus clock which voltage range must I consider?
