Note 1 Rate of voltage change must be less then 0 5 V ms
Note 2 Supply current is measured after running 2000 cycles with a crystal resonator oscillator inputs at rails and outputs open
Note 3 The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations Test conditions All inputs tied to V_CC L C and G0–G5 configured
as outputs and set high The D port set to zero The clock monitor and the comparators are disabled
