The Counter/Timer 8 Control register (see
T8 timer.
Writing 1 to CTR0[5] is the only way to reset the Terminal Count status condition. Reset
this bit before using/enabling the counter/timers.

You must be careful when using the OR or AND commands to manipulate CTR0, bit 5 and
CTR1, bits 0 and 1 (DEMODULATION Mode). These instructions use a Read-Modify-
Write sequence in which the current status from the CTR0 and CTR1 registers is ORed or
ANDed with the designated value and then written back into the registers.
Example: When the status of bit 5 is 1, a timer reset condition occurs.
