| abstract | (57) [PROBLEMS] To realize an interface control circuit capable of efficiently receiving processing request signals of a plurality of blocks synchronously operating according to clock signals of different frequencies, and to realize an emulation unit or the like built in a microcontroller or the like. Increase processing speed and reduce the time required for emulation using the same. On the other hand, a cycle of a clock signal TCLK having a relatively high frequency is coupled to a peripheral bus PB having a cycle of a clock signal PCLK having a relatively high frequency as a substantial bus cycle. In a microcontroller or the like incorporating an emulation unit coupled to a JTAG bus, which is a substantial bus cycle, a processing request signal TREQ output from, for example, a TAP controller on the JTAG bus side is converted to a clock signal TCL. The signal is taken into the latch LTRQ in accordance with the clock signal PCLK directly without being synchronized with K, synchronized, and received. |
