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.)

Reserved, should be cleared.
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.
