Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To eliminate a lock time by selecting programmably clock signals with different frequencies while setting fixed frequency division to a frequency divider circuit in the inside of a PLL so as to keep the lock state of the PLL. SOLUTION: A frequency control register 7 switches the output level of frequency division control signals 8, 9 and a clock selector signal 10 in response to a setting condition. When an external event takes place and it is required to apply high speed interrupt processing synchronously therewith, the frequency division control signal 9 is set active to the frequency control register 7 in the program. When a frequency division ratio is switched in a frequency divider circuit 12, an input clock fd to a clock selector 6 is switched immediately to a frequency of 25MHz and a system clock 11 being a clock source fc is momentarily set to 25MHz and the program processing is operated in the high speed mode. In the frequency changeover operation for a series of system clocks 11, the lock state of the PLL is maintained.

Abstract: PROBLEM TO BE SOLVED: To save power consumption and to execute a pull-up operation at a high speed by suppressing the rapid increase of a gate leak current, when a power voltage is larger than a gate-on voltage in a semiconductor logical circuit using a Schottky gate-type FET. SOLUTION: This circuit is composed of a push-pull circuit 100 and a DCFL (direct couple FET logic) logical circuit 200 and a transfer gate 6, the output b of the DCFL logical circuit 200 is connected to the gate of FET2 at a low- voltage power source side of the FETs constituting the push-pull circuit 100. The transfer gate 6 is connected to the input of the DCFL logical circuit 200 and the gate of FET1 at a high-voltage power source side of the FETs constituting the push-pull circuit 100 and its gate potential is adopted as a gate diode on voltage VF + a threshold value voltage VT. Thus, when the input IN becomes larger than VF, FET6 is turned off so that the gate leak current of FET3 is removed, and also the high level of the input IN is not clamped in VF. Therefore, the high level of the gate in FET1 becomes large, so that pull-up ability becomes large.
