Timer Interface Module A (TIMA)
11.10 I/O Registers
The following I/O registers control and monitor operation of the TIMA:
• TIMA status and control register (TASC)
• TIMA counter registers (TACNTH:TACNTL)
• TIMA counter modulo registers (TAMODH:TAMODL)
• TIMA channel status and control registers (TASC0, TASC1,
TASC2, and TASC3)
• TIMA channel registers (TACH0H:TACH0L, TACH1H:TACH1L,
TACH2H:TACH2L, and TACH3H:TACH3L)
11.10.1 TIMA Status and Control Register
The TIMA status and control register does the following:
• Enables TIMA overflow interrupts
• Flags TIMA overflows
• Stops the TIMA counter
• Resets the TIMA counter
• Prescales the TIMA counter clock
