Bit 7: Transmit Manual Error Insert (TMEI).
When PORT.CR1:MEIMS = 0, this bit is used to insert errors in all
blocks where block-level MEIMS = 1. Error(s) are inserted at the next opportunity after this bit transitions from low
to high. See Section 8.7.5. Note: This bit should be set low immediately after each error insertion.
Bit 6: Transmit Manual Error Insert Mode Select (MEIMS).
This bit specifies the source of the error insertion
signal for all block-level error generators that have block-level MEIMS = 1. See Section 8.7.5.
0 = Port-level error insertion via PORT.CR1:TMEI
1 = Global error insertion as specified by GLOBAL.CR1:MEIMS
Bit 5: Port Performance Monitor Update Mode (PMUM).
This bit specifies the source of the performance
monitoring update signal for all blocks that have block-level PMUM = 1. See Section 8.7.4.
0 = Port-level PM update via PORT.CR1:PMU
1 = Global PM update as specified by GLOBAL.CR1:GPM[1:0]
Bit 4: Port Performance Monitor Register Update (PMU).
When PORT.CR1:PMUM = 0, this bit is used to
update all of the performance monitor registers where block-level PMUM = 1. When this bit transitions from low to
high, all configured performance monitoring registers are updated with the latest counter values, and all associated
counters are reset. This bit should remain high until the performance monitor update status bit (PORT.SR:PMS)
goes high, and then it should be brought back low, which clears the PMS status bit. If a counter increment occurs
at the exact same time as the counter reset, the counter is loaded with a value of one, and the “counter is non-
zero” latched status bit is set. See Section 8.7.4.
