Field
Counter_INT_Mask
P34_Out
*Indicates the value upon Power-On Reset.
Note:
Caution:
T8 Enable
This field enables T8 when set (written) to 1.
Single/Modulo-N
When set to 0 (Modulo-N), the counter reloads the initial value when the terminal count is
reached. When set to 1 (single-pass), the counter stops when the terminal count is reached.
Timeout
This bit is set when T8 times out (terminal count reached). To reset this bit, write 1 to its
location.
Ensure to manipulate CTR0, bit 5 and CTR1, bits 0 and 1 (DEMODULATION Mode)
when using the OR or AND commands. 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.
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 timeout.
Writing a 1 is the only way to reset the Terminal Count status condition. Reset this bit
before using/enabling the counter/timers.
The first clock of T8 might not have complete clock width and can occur any time when
enabled.
