b Bit Name Function R W
8 TINIS33 (TIN33 interrupt request status bit) 0: Interrupt not requested R(Note 1)
9 TINIS32 (TIN32 interrupt request status bit) 1: Interrupt requested
10 TINIS31 (TIN31 interrupt request status bit)
11 TINIS30 (TIN30 interrupt request status bit)
12 TINIM33 (TIN33 interrupt request mask bit) 0: Enable interrupt request R W
13 TINIM32 (TIN32 interrupt request mask bit) 1: Mask (disable) interrupt request
14 TINIM31 (TIN31 interrupt request mask bit)
15 TINIM30 (TIN30 interrupt request mask bit)
Note 1: Only writing "0" is effective. Writing "1" has no effect; the bit retains the value it had before the write.
Note: • TIN24–TIN29 do not have interrupt functions, so that their status and mask registers are nonexistent.
