Software can stop a certain FIFO to update TOP_CTRL.TSENSE*_DATA1, TOP_CTRL.TSENSE*_DATA2, and TOP_CTRL.TSENSE*_DATA3 with new temperature and timestamp values by setting one of the FREEZE bits in the TOP_CTRL.TSENSE0_CNTL and TOP_CTRL.TSENSE1_CNTL registers to 1. These FIFO_FREEZE bits are automatically cleared by hardware after the FIFOs are cleared.
Each FIFO is cleared by setting to 1 one of the FIFO_CLEAR bits in the TOP_CTRL.TSENSE0_CNTL and TOP_CTRL.TSENSE1_CNTL registers. These FIFO_CLEAR bits are also automatically set by hardware to 0 after the FIFOs clearing procedure completes.
Additionally TOP_CTRL.TSENSE0_ACCU and TOP_CTRL.TSENSE1_ACCU registers store the accumulated temperature values. This are cleared by setting one of the ACCU_CLEAR bits to 1 in the TOP_CTRL.TSENSE0_CNTL and TOP_CTRL.TSENSE1_CNTL registers.
