device detects a clock at FTCLK. The HRCLK checks for the presence of the FTCLK. On reset, both the LOTC
and LORC status bits will be set and then immediately cleared if the clock is present.
Bit 11: Loss Of Receive Clock Detected (LORC). This read-only real-time status bit will be set to a one when the
device detects that the HRCLK clock has not toggled for 200ns (±100ns). This bit will be cleared when a clock is
detected at the HRCLK input. The setting of this status bit can cause a hardware interrupt to occur if the LORC bit
in the Interrupt Mask for MSR (IMSR) register is set to a one. The interrupt will be allowed to clear when the
device detects a clock at HRCLK. The FTCLK checks for the presence of the HRCLK. On reset, both the LOTC
and LORC status bits will be set and then immediately cleared if the clock is present.
Bit 12: State of the T3E3MS Input Signal (T3E3MS). This read-only real-time status bit reflects the current state
of the external T3E3MS input signal. This status bit cannot generate an interrupt.
Bit 13: State of the G.747E Input Signal (G.747E). This read-only real-time status bit reflects the current state of
the external G.747E input signal. This status bit cannot generate an interrupt.
