12.8 Oscillators and clocks

The

CC2430 has one internal system clock.

The source for the system clock can be either

a 16 MHz high-frequency RC oscillator or a 32

MHz crystal oscillator. Clock control is

performed using the CLKCON SFR register

described in section 13.10.

The system clock also feeds all 8051

peripherals (as described in section 6).

The choice of oscillator allows a trade-off

between high-accuracy in the case of the

crystal oscillator and low power consumption

when the high-frequency RC oscillator is used.

Note that operation of the RF transceiver

requires that the crystal oscillator is used.

12.9 Debug Interface

The

CC2430 includes a debug interface that

provides a two-wire interface to an on-chip

debug module. The debug interface allows

programming of the on-chip flash and it

provides access to memory and register

contents

and

debug

features

such

breakpoints,

single-stepping

and

modification.

The debug interface uses the I/O pins P2_1 as

Debug Data and P2_2 as Debug Clock during

Debug mode. These I/O pins can be used as

general purpose I/O only while the device is

not in Debug mode. Thus the debug interface

does not interfere with any peripheral I/O pins.

12.9.1 Debug Mode

Debug mode is entered by forcing two rising

edge transitions on pin P2_2 (Debug Clock)

while the RESET_N input is held low.

While in Debug mode pin P2_1 is the Debug

Data bi-directional pin and P2_2 is the Debug

Clock input pin.
