The corresponding Timer A counter has not reached its terminal count.
The corresponding Timer A counter has reached its terminal count. These status
bits (not the interrupt enable bits) are cleared by the read of this register, as is the
Timer A interrupt.
The corresponding Timer A interrupt is disabled.
The corresponding Timer A interrupt is enabled.
The clock input for Timer A is disabled.
The clock input for Timer A is enabled.
These bits are reserved and should be written with zero.
The main clock for Timer A is the peripheral clock (perclk).
The main clock for Timer A is the peripheral clock divided by two (perclk/2).
