NOTE:
1. The
LBO, TMS, TDI, TCK and TRST pins will be internally pulled to VDD and the ZZ pin will be internally pulled to VSS if they are not actively driven in the application.
NOTES:
1. All values are maximum guaranteed values.
2. At f = fMAX, inputs are cycling at the maximum frequency of read cycles of 1/tCYC while
ADSC = LOW; f=0 means no input lines are changing.
3. For I/Os VHD = VDDQ - 0.2V, VLD = 0.2V. For other inputs VHD = VDD - 0.2V, VLD = 0.2V.
