16. Power-on reset
The ISP1181 has an internal power-on reset (POR) circuit. Input pin RESET can be
directly connected to V
CC
. The clock signal on output CLKOUT starts 0.5 ms after
power-on and normally requires 3 to 4 ms to stabilize.
The triggering voltage of the POR circuit is 2.0 V nominal. A POR is automatically
generated when V
CC
goes below the trigger voltage for a duration longer than 50
μ
s.
A hardware reset disables all USB endpoints and clears all ECRs, except for the
control endpoint which is fixed and always enabled.
Section 9.3
explains how to
(re)initialize the endpoints.
If enabled, the 24 kHz LazyClock frequency will be output on pin CLKOUT during ‘suspend’ state.
