6 / 72 page DC Electrical Characteristics (Continued) Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at VCC or GND, and outputs open. Note 4: The HALT mode will stop CKI from oscillating in the Crystal configurations. Halt test conditions: All inputs tied to VCC; Port C, G, E, F, L, M and N I/Os con- figured as outputs and programmed low; D outputs programmed high. Parameter refers to HALT mode entered via setting bit 7 of the Port G data register. Part will pull up CKI during HALT in crystal clock mode. Both CAN main comparator and the CAN Wakeup comparator need to be disabled. Note 5: . HALT and IDLE current specifications assume CAN block comparators are disabled. Note 6: Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages greater than VCC and the pins will have sink current to VCC when biased at voltages greater than VCC (the pins do not have source current when biased at a voltage below VCC). The effective resistance to VCC is 750Ω (typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V. Note 7: Condition and parameter valid only for part in HALT mode. Note 8: Parameter characterized but not tested.

The device can support a bus speed of up to 1 Mbit/S with a 10 MHz oscillator and 2 byte messages. The 1M bus speed refers to the rate at which protocol and data bits are transferred on the bus. Longer messages require slower bus speeds due to the time required for software intervention between data bytes. The device will support a maximum of 125k bits/s with eight byte messages and a 10 MHz oscillator. For device testing purpose of all AC parameters, VOH will be tested at 0.5*VCC. Note 9: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs. Note 10: Parameter not tested.
