Figure 15-1: Condition 1
Condition 1 is satisfied when S0=1 at the falling edge of S1. The bit UsrtCond1 in RegUsrtCond1 is set when the
condition 1 is detected and the USRT interface is enabled (UsrtEnable=1). Condition 1 is asserted for both modes
(receiver and transmitter). The UsrtCond1 bit is read only and is cleared by all reset conditions and by writing any
data to its address.
Condition 1 occurrence also generates an interrupt on Irq_cond1.
