(4) Timer status register 0n (TSR0n)
Symbol
TSR0n
TSR0n indicates the overflow status of the counter of channel n.
TSR0n is valid only in the capture mode (MD0n3 to MD0n1 = 010B) and capture & one-count mode (MD0n3 to
MD0n1 = 110B). It will not be set in any other mode. See Table 6-3 for the operation of the OVF bit in each
operation mode and set/clear conditions.
TSR0n can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of TSR0n can be set with an 8-bit memory manipulation instruction with TSR0nL.
Reset signal generation clears this register to 0000H.
Remark
When OVF = 1, this flag is cleared (OVF = 0) when the next value is captured without overflow.

Table 6-3. OVF Bit Operation and Set/Clear Conditions in Each Operation Mode
The OVF bit does not change immediately after the counter has overflowed, but changes upon the
subsequent capture.
