Timer Interface A (TIMA)
11.8 I/O Registers
11.8.1 TIMA Status and Control Register
Advance Information
218
Address:
These input/output (I/O) registers control and monitor TIMA operation:
The TIMA status and control register:
TOF — TIMA Overflow Flag
Reset:

This read/write flag is set when the TIMA counter resets to $0000 after
reaching the modulo value programmed in the TIMA counter modulo
registers. Clear TOF by reading the TIMA status and control register
