This register allows reading the counter value of the 16-bit free-run timer. The counter value is
cleared to 0000 at reset. To set a timer value, write it to this register in the stop status (STOP =
1). Access this register in units of words. The 16-bit free-run timer is initialized by following one
of the methods below.
• Initialization by reset
• Initialization by clearing the control status register (CLR)
• Initialization by matching a compare clear register (Ch. 0 compare register) value with a timer
counter value (A mode must be set.)
