Caution: Writing a 1 is the only way to reset the Terminal Count

status condition. Therefore, you must reset this bit before

using/enabling the counter/timers.

Note: Care must be taken 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.

For example, when the status of bit 5 is 1, a timer reset condition occurs.

T8 Clock

This bit defines the frequency of the input signal to T8.

Capture_INT_Mask

Set this bit to allow an interrupt when data is captured into either LO8 or HI8 upon

a positive or negative edge detection in demodulation mode.

Counter_INT_Mask

Set this bit to allow an interrupt when T8 has a time-out.

P34_Out

This bit defines whether P34 is used as a normal output pin or the T8 output.

CTR1(D)01h

This bit controls the functions in common with the T8 and T16.
