1. A method of operating a wireless device including a power supply source and a non-volatile memory unit, the method comprising:
- receiving a wireless signal from a host device, wherein the wireless signal is defined in accordance with a serial data communication protocol;
extracting a write command and payload data from the wireless signal;
receiving and storing the payload data in the non-volatile memory unit in response to the write command;
while receiving and storing the payload data, extracting a power measurement command from the wireless signal;
detecting a power state for the power supply source in response to the power measurement command and generating a power state indication based on the detected power state;
if the power state indication indicates the power state is above a threshold value, continuing the receiving and storing of the payload data until all of the payload data is received and stored; and
if the power state indication indicates the power state is below the threshold value, transmitting a power deficient indication from the wireless device to the host and interrupting the receiving and storing of the payload data.

8. A method of operating a wireless device including a power supply source and a non-volatile memory unit, the method comprising:
-
receiving a wireless signal from a host device, wherein the wireless signal is defined in accordance with a serial data communication protocol; extracting a read command from the wireless signal; retrieving payload data from the non-volatile memory unit in response to the read command and transmitting the payload data to the host; during the retrieving and transmitting of the payload data, extracting a power measurement command from the wireless signal; detecting a power state for the power supply source in response to the power measurement command and generating a power state indication based on the detected power state; if the power state indication indicates the power state is above a threshold value, continuing the retrieving and transmitting of the payload data until all of the payload data is transmitted; and if the power state indication indicates the power state is below the threshold value, transmitting a power deficient indication from the wireless device to the host and interrupting the retrieving and transmitting of the payload data. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
