STATE

grammar

STATE [pathstate1 [ pathstate2 ... [ pathstaten]]] state_state;

describe

Force the target IEEE 1149.1 Bus to a stable IEEE 1149.1 state .

Parameters

Parameter name	describe	remarks
pathstate 1-n	Optional IEEE 1149.1 state , Clearly described TAP State diagram path , Specify the state transition path in turn . Valid states include ：RESET、IDLE、DRSELECT、DRCAPTURE、DRSHIFT、DRPAUSE、DREXIT1、DREXIT2、DRUPDATE、IRSELECT、IRCAPTURE、IRSHIFT、IRPAUSE、IREXIT1、IREXIT2 and IRUPDATE. The order of states in the state list should be the same as TAP Consistent state diagram .
state_state	IEEE 1149.1 Bus steady state includes ：IRPAUSE、DRPAUSE、RESET and IDLE

give an example

Force the bus from its current state DRPAUSE To DRPAUSE

STATE DRPAUSE

Follow the specified path from DRPAUSE To IRPAUSE

STATE DREXIT2 DRUPDATE DRSELECT IRSELECT IRCAPTURE IREXIT1 IRPAUSE;
