Document Type and Number:
Japanese Patent JP5890251
Kind Code:
B2
Abstract:
A command sequence is restarted from the middle even when supply of power supply voltage to an internal circuit in a wireless tag is temporarily stopped (a power flicker occurs). A register or a cache memory included in a signal processing circuit in the wireless tag continues to retain data even after the supply of power supply voltage is stopped. After the power flicker occurs, the signal processing circuit in the wireless tag is returned to the state before the supply of power supply voltage is stopped and can restart signal processing. Consequently, the command sequence can be restarted from the middle.
