When the TJITT_TEST bit (b5, T1/J1-021H,...) is ‘0’, these bits represent the current interval between the read and write pointer of the FIFO.
When the TJITT_TEST bit (b5, T1/J1-021H,...) is ‘1’, these bits represent the P-P interval between the read and write pointer of the FIFO since
These bits will be cleared if a ’1’ is written to the register.
When the RJITT_TEST bit (b5, T1/J1-027H,...) is ‘0’, these bits represent the current interval between the read and write pointer of the FIFO.
When the RJITT_TEST bit (b5, T1/J1-027H,...) is ‘1’, these bits represent the P-P interval between the read and write pointer of the FIFO since
These bits will be cleared if a ’1’ is written to the register.
