Data Sheet
A low signal on the RST pin or setting the RES_TR bit in the SRES register to
’1’ resets also the layer-1 statemachine. The reset signals should be applied
for a minimum of 2 DCL clock cycles. The function of these reset events is
identical to the C/I code RES concerning the state machine.
