Bit 0: Performance Monitoring Update Status (PMS). This bit is set when the PMS bits are set in all of the port
functional blocks that are configured for port-level update control (i.e., all blocks that have PMUM = 1). Blocks that
have PMUM = 0 have no effect on this bit. In port-level software update mode, the port update request bit
(PORT.CR1:PMU) should be held high until this status bit goes high. See Section 8.7.4.
Bit 8: Transmit Clock Activity Status Latched (TCLKL). This bit is set when the signal on the TCLK pin used by
this port (TCLK n when TCC = 0, TCLK1 when TCC = 1) is active. When set, this bit causes an interrupt if interrupt
enables PORT.SRIE:TCLKIE, PORT.ISRIE:PSRIE, and GLOBAL.ISRIE: PnISRIE are all set.
Bit 0: Performance Monitoring Update Status Latched (PMSL). This bit is set when the PORT.SR:PMS status
bit changes from low to high. When set, this bit causes an interrupt if interrupt enables PORT.SRIE:PMSIE,
PORT.ISRIE:PSRIE and GLOBAL.ISRIE:PnISRIE are all set. See Section 8.7.4.
