When the TJITT_TEST bit (b5, E1-021H) is ‘0’, these bits represent the current interval between the read and write pointer of the FIFO.
When the TJITT_TEST bit (b5, E1-021H) is ‘1’, these bits represent the P-P interval between the read and write pointer of the FIFO since last
These bits will be cleared if a ’1’ is written to the register.
When the RJITT_TEST bit (b5, E1-027H) is ‘0’, these bits represent the current interval between the read and write pointer of the FIFO.
When the RJITT_TEST bit (b5, E1-027H) is ‘1’, these bits represent the P-P interval between the read and write pointer of the FIFO since last
These bits will be cleared if a ’1’ is written to the register.
