SPI REG Fault Table PWUP

Address

0x12

XX_POWERUP_FAULT: 1: means Power-on failed

0: means Power-on succeeded or regulator disabled by OTP

REC_CNT: the counter of times that FSM into REC; will be cleared in STANDBY. If inf_retrail_en=1, REC_CNT is

always 0.

PLL_LOCK_STATUS: this bit is reporting the internal PLL locking status. When "1", the output frequency of the PLL is locked

and stable. When "0", the PLL is not yet stable or off.

WD_FAIL: watchdog fail flag, read and clear; Include normal WDI WD or SPI WD.

0: no fail

1: fail

ABIST_ERR: ABist fail flag, read only.

0: no fail

1: fail

SAF_CRC_FAILED: read only.

0: no fail

1: fail

LBIST_ERR: read only.

0: no fail

1: fail
