(4) Timer status register mn (TSRmn)
TSRmn
Symbol
TSRmn indicates the overflow status of the counter of channel n.
TSRmn is valid only in the capture mode (MDmn3 to MDmn1 = 010B) and capture & one-count mode (MDmn3
to MDmn1 = 110B). It will not be set in any other mode. See Table 7-3 for the operation of the OVF bit in each
operation mode and set/clear conditions.
TSRmn can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of TSRmn can be set with an 8-bit memory manipulation instruction with TSRmnL.
Reset signal generation clears this register to 0000H.
Remark
F01D0H, F01D1H (TSR10) to F01D6H, F01D7H (TSR13)
When OVF = 1, this flag is cleared (OVF = 0) when the next value is captured without overflow.

Table 7-3. 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.
Timer operation mode
Overflow does not occur.
