Bits 12 to 9: Global One-Second Reference Source (G1SRS[3:0]). These bits determine the source for the
internally generated one second reference. The source is selected from one of the CLAD clocks or from one of the
port transmit clocks. See Section 8.7.2.
Bit 8: Global One-Second Reference Output Enable (G1SROE). This bit determines whether the GPIOB3 pin is
used to output the global one second reference signal. See Section 8.7.2.
Bit 7: Transmit Manual Error Insert (TMEI). When GLOBAL.CR1:MEIMS = 0, this bit is used to insert errors in all
blocks in all ports where block-level MEIMS = 1 and PORT.CR1: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: Manual Error Insert Mode Select (MEIMS). This bit specifies the source of the manual error insertion signal
for all block-level error generators that have block-level MEIMS = 1 and PORT.CR1:MEIMS = 1. See Section 8.7.5.
Bits 5 and 4: Global Performance Monitor Update Mode (GPM[1:0]). These bits specify the source of the
performance monitoring update signal for all blocks that have block-level PMUM = 1 and PORT.CR1:PMUM = 1.
See Section 8.7.4.
