In system interface multiplex mode signals on RDO2-4 and RSIG2-4
are undefined, while signals on SCLKR2-4, SYPR2-4, SCLKX2-4,
SYPX2-4, XDI2-4 and XSIG2-4 are ignored.
Configure SEC / FSC Port
The FSC pulse is generated if the DCO-R circuitry of the selected
channel is active (CMR2.IRSC = 1 or CMR1.RS1/0 = 10 or 11).

SEC / FSC Source
One of the four internal generated dejittered 8 kHz clocks or second
timers (SEC) are output on port SEC / FSC.
GPC1.CSFP1 = 1:
00 … FSC : 8 kHz sourced by channel 1
01 … FSC : 8 kHz sourced by channel 2
10 … FSC : 8 kHz sourced by channel 3
11 … FSC : 8 kHz sourced by channel 4
GPC1.CSFP1 = 0:
00 … SEC : second timer sourced by channel 1
01 … SEC: second timer sourced by channel 2
10 … SEC: second timer sourced by channel 3
11 … SEC: second timer sourced by channel 4
