8.7.2 One-Second Reference Generator
The one-second reference signal can be used to update performance monitoring registers on a precise one-
second interval. The generated internal signal is a 50% duty cycle signal that is divided down from the indicated
reference signal. The low to high edge on this signal sets the GLOBAL.SRL:1SREFL latched one-second bit, which
can generate an interrupt if enabled. The low to high edge is used to initiate a performance monitor register update
when GLOBAL.CR1:GPM[1:0] = 1X. The internal one-second reference can be output on the GPIOB3 pin by
setting GLOBAL.CR1:G1SROE. The source for the one second reference is set by GLOBAL.CR1:G1SRS[3:0]. The
DS3, E3, and STS-1 reference clocks are sourced from the CLAD, if the CLAD is configured to generate them, or
from the CLKA, CLKB ,and CLKC pins, respectively.
