TIMESLOT_OFFSET_x Time Slot x offset in 64 × the number of 1 MHz low

frequency oscillator cycles or 2 × the number of 32 kHz

low frequency oscillator cycles.

0x0101 TS_PATH_A

[15:12] PRE_WIDTH_x

Preconditioning duration for Time Slot x. This value is in

2 μs increments. A value of 0 skips the preconditioning

state. Default is 8 μs.

0x0181 TS_PATH_E

TS_GPIO_x

Time slot specific value for Time Slot x. When GPIOOUTx is

set to 0x10 and TS_GPIO_x is set to 1, the GPIO selected

by GPIOOUTx outputs a 1 while the time slot selected by

TS_GPIO_x is active. The GPIO returns to the

TS_GPIO_SLEEP value at the end of the time slot.
