Note 2: Maximum rate of voltage change must be less than 0.5 V/ms

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; L, and G port I/Os configured as outputs

and programmed low; D outputs programmed low. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register. Part will pull up CKI during

HALT in crystal clock mode.

Note 5: HALT and IDLE current specifications assume CAN block and comparators are disabled.
