Table 4-235 STC_STCGCR0 Register Field Descriptions

Bit	Field	Type	Reset	Description
31:16	INTCOUNT_B16	R/W	1h	Number of intervals of the self test run [RWP - Read, Priviledge Mode Write only] Count of intervals that need to be covered for a specific selftest run. The selftest controller sends out complete indication once it runs all of the intervals programmed in this field. INTCOUNT_B16=0 is an invalid configuration for a selftest.
15:11	NU0	R	0h	Reserved bits
10:8	CAP_IDLE_CYCLE	R/W	1h	Idle cycles before and after capture clock [RWP - Read, Priviledge Mode Write only] Idle Cycles before and after capture clock. This value is used to insert that many idle cycles in the Capture phase. Programmable idle cycles allow implementation flexibility on SCAN_EN signal at chip level based on the size of the UUT and timing requirements.
7:5	SCANEN_HIGH_CAP_IDLE_CYCLE	R/W	1h	Idle cycles before and after capture clock [RWP - Read, Priviledge Mode Write only]. *NOT BYTE ACCESSIBLE Idle Cycles between scan_en going high to func_clk_en generation and scan_en going high to misr_log_en generation. This value is used to insert that many idle cycles in the shift clock [scan_en going high to func_clk_en generation] and misr_log_clk [scan_en going high to misr_log_en generation] generation. Programmable idle cycles allow implementation flexibility on SCAN_EN signal at chip level based on the size of the UUT and timing requirements.
4:2	NU1	NU1	0h	Reserved bits
1:0	RS_CNT_B1	R/W	0h	Restart/Continue or preload [RWP - Read, Priviledge Mode Write only] This bit specifies the selftest controller whether to continue the run from next interval onwards, restart from ROM address 0 or preload from a prescribed interval. This bit gets reset after the completion of selftest run. 00 = Continue NSTC run from previous interval 01 = Restart NSTC run from ROM address 0 1X = Start from segment number specified in STC_SEGPLR register
