The default value for GDO0 is a 125 to 146 kHz clock output (XOSC frequency divided by 192). Because

the XOSC is turned on at power-on-reset, this can be used to clock the MCU in systems with only one

crystal. When the MCU is up and running it can change the clock frequency by writing to

IOCFG0.GDO0_CFG.

An on-chip analog temperature sensor is enabled by writing the value 128 (0x80h) to the

IOCFG0.GDO0_CFG register. The voltage on the GDO0 pin is then proportional to temperature. See

Section 4.9 for temperature sensor specifications.

DESCRIPTION

0 (0x00)

Reserved – defined on the transceiver version (CC1101).

1 (0x01)

Reserved – defined on the transceiver version (CC1101).

Associated to the TX FIFO: Asserts when the TX FIFO is filled at or above the TX FIFO threshold. De-asserts

2 (0x02)

when the TX FIFO is below the same threshold.

Associated to the TX FIFO: Asserts when TX FIFO is full. De-asserts when the TX FIFO is drained below the

3 (0x03)

TX FIFO threshold.

4 (0x04)

Reserved – defined on the transceiver version (CC1101).

5 (0x05)

Asserts when the TX FIFO has underflowed. De-asserts when the FIFO is flushed.

Asserts when sync word has been sent, and de-asserts at the end of the packet. In TX the pin will also de-

6 (0x06)

assert if the TX FIFO underflows.

7 (0x07)

Reserved – defined on the transceiver version (CC1101).

8 (0x08)

Reserved – defined on the transceiver version (CC1101).

9 (0x09)

Reserved – defined on the transceiver version (CC1101).

Lock detector output. The PLL is in lock if the lock detector output has a positive transition or is constantly

10 (0x0A)

logic high. To check for PLL lock the lock detector output should be used as an interrupt for the MCU.

Serial Clock. Synchronous to the data in synchronous serial mode.

11 (0x0B)

In TX mode, data is sampled by CC1150 on the rising edge of the serial clock when GDOx_INV=0.

12 (0x0C)

Reserved – defined on the transceiver version (CC1101).

13 (0x0D)

Reserved – defined on the transceiver version (CC1101).

14 (0x0E)

Reserved – defined on the transceiver version (CC1101).

15 (0x0F)

Reserved – defined on the transceiver version (CC1101).

16 (0x10)

Reserved – used for test.

17 (0x11)

Reserved – used for test.

18 (0x12)

Reserved – used for test.

19 (0x13)

Reserved – used for test.

20 (0x14)

Reserved – used for test.

21 (0x15)
