Prescaler bits. Select the prescaler divisor for the GPT counter.
000 Prescaler divisor 1
001 Prescaler divisor 2
010 Prescaler divisor 4
011 Prescaler divisor 8
100 Prescaler divisor 16
101 Prescaler divisor 32
110 Prescaler divisor 64
111 Prescaler divisor 128
Note: The newly selected prescaled clock does not take effect until the next synchronized edge of the prescaled clock
when the clock count transitions to 0x0000.)

Channel flags. A channel flag is set when an input capture or output compare event occurs. These bits are read
anytime, write anytime (writing 1 clears the flag, writing 0 has no effect).
Note: When the fast flag clear all bit, GPTSCR1[TFFCA], is set, an input capture read or an output compare write
clears the corresponding channel flag. When a channel flag is set, it does not inhibit subsequent output compares
or input captures.
