Radio communication device
First Claim
1. A radio communication device comprising:
- a signal generator outputting a signal whose frequency is uniquely decided by frequency data set therein;
a control section outputting first data to the signal generator and setting the first data therein as frequency data, the control section being able to transition among an access unimplementing state where the control section does not access the signal generator, an access stand-by state where the control section waits for access to the signal generator, and an access implementing state where the control section accesses the signal generator; and
a signal processing section outputting second data to the signal generator and setting the second data therein as frequency data, the signal processing section being able to transition between an access allowed state where the signal processing section is allowed to access the signal generator and an access inhibited state where the signal processing section is inhibited from accessing the signal generator;
wherein the control section transfers, to the signal processing section, a signal indicative of a desire to transition to the access implementing state and a signal indicative of transition of the control section from the access implementing state; and
wherein the signal processing section transfers, to the control section, a signal indicative of transition of the signal processing section between the access allowed state and the access inhibited state.

Abstract
A signal generator outputs a signal whose frequency is uniquely decided by frequency data set therein. A control section can set first data in the frequency generator as frequency data. The control section can transition among an access unimplementing state, an access stand-by state, and an access implementing state. A signal processing section can set second data in the signal generator as frequency data. The signal processing section can transition between an access allowed state and an access inhibited state. The control section transfers, to the signal processing section, a signal indicative of a desire to transition to the access implementing state and a signal indicative of transition of the control section from the access implementing state. The signal processing section transfers, to the control section, a signal indicative of transition of the signal processing section between the access allowed state and the access inhibited state.

8. A radio communication device comprising:
-
a PLL circuit including a frequency divider having a controllable frequency division ratio; a CPU accessible to the frequency divider to control the frequency division ratio; and a DSP accessible to the frequency divider to control the frequency division ratio; wherein in cases where the CPU outputs an access request signal to the DSP when the DSP accesses the frequency divider, the DSP suspends accessing the frequency divider in response to the access request signal and thereafter outputs an access allowance signal to the CPU, and wherein the CPU starts accessing the frequency divider in response to the access allowance signal. - View Dependent Claims (9)
