9.2 MCAN_TSU_TSS1 not reset after a MCAN_TSU_TSx read

TSL[15:0] and TSN[15:0] in MCAN TSU Timestamp Status 1 (MCAN_TSU_TSS1) are not reset after reading a MCAN TSU Timestamp Status (MCAN_TSU_TSx) register.

Work Around

Proceed as follows:
  1. Read MCAN_TSU_TSx.
  2. For each bit set, read the corresponding MCAN_TSU_TSx and save the values.
  3. Write the same MCAN_TSU_TSx register with value ‘0’ to reset the corresponding bit in MCAN_TSU_TSS1.
