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 V_CC 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 V_CC; 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.
