DATASHEET
The LED Pulse 1 Period register determines the overall period of a pulse operation as determined by
the LED_CTL registers (see Table 5.50 - setting 01b). Each LSB represents 32ms so that a setting of
14h (20d) would represent a period of 640ms. The total range is from 32ms to 4.06 seconds as shown
The Pulse 1 operation is shown in Figure 5.1.
