T8 TRANSMIT Mode
REF
Based on register bits CTR1[5:4], a pulse is generated at when a rising edge, falling edge,
or any edge is detected. Glitches in the input signal are filtered out if they are shorter than
the glitch filter width specified in register bits CTR1[3:2].

The timers can be configured to operate in following modes:
•

•
•
Before T8 is enabled, the output of T8 depends on CTR1, bit 1. If the bit is 0, T8_OUT is
1; if it is 1, T8_OUT is 0. See
