16.4 Interrupts map
16.5 Conditional edge detection 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.
16.6 Conditional edge detection 2
Condition 2 is satisfied when S0=1 at the rising edge of S1. The bit UsrtCond2 in RegUsrtCond2 is set when the
condition 2 is detected and the USRT interface is enabled. Condition 2 is asserted for both modes (receiver and
transmitter). The UsrtCond2 bit is read only and is cleared by all reset conditions and by writing any data to its
address.
Condition 2 occurrence also generates an interrupt on Irq_cond2.
