When interfacing to a Maxim T1/E1 transceiver as shown, the device should be programmed to invert the RCLK
input for each serial interface (LI.RCR1.RCLKINV = 1).
Because the first gapped transmit clock input edge after the transmit sync pulse is coincident with the start of the
first byte of user data, the transmit sync setup control bits must be configured for a sync pulse that arrives zero
clock cycles early ( LI.TCR.TS_SETUP[1:0] = 00).
