Abstract
A semiconductor device includes a reset sequence circuit, a latch circuit, and a reset control circuit. The reset sequence circuit is activated by receiving an externally input signal when a reset operation is started and outputs a first trigger signal. The latch circuit is capable of holding selection information on circuits capable of being reset. The selection information is externally input. The reset control circuit outputs a reset signal on the basis of the selection information held in the latch circuit in response to a power-on reset signal and the first trigger signal output from the reset sequence circuit.
Claims18
A semiconductor device comprising:
- a reset sequence circuit which is activated by receiving an externally input signal when a reset operation is started and outputs a first trigger signal;
- a latch circuit which is capable of holding selection information on circuits capable of being reset, the selection information being externally input;
- and
- a reset control circuit which outputs a reset signal on the basis of the selection information held in the latch circuit in response to a power-on reset signal and the first trigger signal output from the reset sequence circuit.
A semiconductor device comprising:
- a latch circuit which is capable of holding selection information on circuits capable of being reset, the selection information being externally input;
- and
- a reset control circuit which outputs a reset signal on the basis of the selection information held in the latch circuit in response to an externally supplied power-on reset signal and a first trigger signal generated according to a signal externally input when a reset operation is started.
