Note 2: t_C = Instruction cycle time (Clock input frequency divided by 10).
Note 3: Maximum rate of voltage change must be < 0.5 V/ms.
Note 4: Supply and IDLE currents are measured with CKI driven with a square wave Oscillator, inputs connected to V_CC and outputs driven low but not connected
to a load.
Note 5: The HALT mode will stop CKI from oscillating in the R/C and the Crystal configurations. CKI is TRI-STATE. Measurement of I_DD HALT is done with device
neither sourcing nor sinking current; with L. F, C, G0, and G2–G5 programmed as low outputs and not driving a load; all outputs programmed low and not driving
a load; all inputs tied to V_CC; WATCHDOG and clock monitor disabled. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register.
Note 6: The ACCESS.Bus interface of the COP8TAB9/TAC9 device implements and meets the timings necessary for interface to the I²C and SMBus protocols at
logic levels. The bus drivers are designed with open-drain outputs, as required for proper bidirectional operation. The device will not meet the AC timing and
current/voltage drive requirements of the full bus specifications.
