• IF counter measurement start command data
• Determines the IF counter measurement time.
* See the “Structure of the IF Counter” section for details.
• Specifies the IF counter input pin (IFIN1 or IFIN2/I1).
• Specifies input or output for the shared function I/O pin (IO2).
• Determines the output state of the BO1 through BO4 and IO2 output ports.
• The data is reset to 0, setting the pins to the open state, after a power on reset.
CTE = 1: Starts the counter
CTE = 0: Resets the counter
LCTS = 0: IFIN1
LCTS = 1: IFIN2/I1
L/I1 = 0: I1 (Input port)
L/I1 = 1: IFIN2 (IF counter 2)
Data = 0: Input port
