What is claimed is:
1. A microcomputer comprising:
an edge detector for detecting a first edge and a second edge of a pulse signal supplied from a remote controller;
effective interval setting means for setting an effective interval after a predetermined time period has elapsed from the time said edge detector detects the first edge; and
interrupt control means for generating an interrupt signal for changing an operation mode from a low current consumption mode to a normal operation mode when said edge detector detects the second edge during the effective interval.
2. A microcomputer comprising:
an edge detector for detecting a first edge, a second edge and a third edge of a pulse signal supplied from a remote controller;
effective interval setting means for setting a first effective interval after a first predetermined time period has elapsed from the time said edge detector detects the first edge, and for setting a second effective interval after a second predetermined time period has elapsed from the time the edge detector detects the second edge during the first effective interval; and
interrupt control means for generating an interrupt signal for changing an operation mode from a low current consumption mode to a normal operation mode when said edge detector detects the third edge during the second effective interval.
3. The microcomputer according to claim 1, wherein said effective interval setting means comprises:
a plurality of reloadable registers for holding count values corresponding to the predetermined time period and to the effective interval; and
a counter for counting each of the count values held in said reloadable registers to determine the predetermined time period and the effective interval.
4. The microcomputer according to claim 2, wherein said effective interval setting means comprises:
a plurality of reloadable registers for holding count values corresponding to the first and second predetermined time periods and to the first and second effective intervals; and
a counter for counting each of the count values held in said reloadable registers to determine the first and second predetermined time periods and the first and second effective intervals.
5. The microcomputer according to claim 1, wherein said effective interval setting means comprises a counter for counting a count value according to count sources corresponding to the predetermined time period and the effective interval, and for setting the predetermined time period and effective interval in response to an overflow of said counter.
6. The microcomputer according to claim 2, wherein said effective interval setting means comprises a counter for counting a count value according to count sources corresponding to the first and second predetermined time periods and to the first and effective intervals, and for setting the first and second predetermined time periods and the first and second effective intervals in response to an overflow of said counter.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
