This is a 16-bit read/write register that allows the CPU to monitor and modify the value of the
Free Running Timer Counter. When the Timer meets TCMR0 (Timer Compare Match Register 0)
+ TTCR0 [6] is set to ‘1’, the TCNTR is cleared to H'0000 and starts running again. In Time-
Trigger mode, this timer can be used as Local Time and TTCR0[6] has to be cleared to work as a
free running timer.
Notes: 1. It is possible to write into this register only when it is enabled by the bit 15 in TTCR0.
• TCNTR (Address = H'08C)
Note: * The register can be written only when enabled in TTCR0[15]. Write operation is not
Bits 15 to 0 — Indicate the value of the Free Running Timer.

This register is a 16-bit read-only register. This register shows Cycle Time = Local Time
(TCNTR) - Reference_Mark (RFMK). In ET mode this register is the exact copy of TCNTR as
RFMK is always fixed to zero.
