Table 7-36 DEVICE_STATUS Register Field Descriptions
Bit Field Type Reset Description
7-5 RESERVED R 0h Reserved
4 INTB_RB R 1h Indicates the level that the device is reading back from INT pin. The reset value of DEVICE_STATUS depends on the status of the INT pin at power-up.
0h = INT pin driven low
1h = INT pin status high
3 OSC_ER R/W1CP 0h Indicates if Oscillator error is detected. Bit is clear when host writes back '1'.
0h = No Oscillator error detected
1h = Oscillator error detected
2 INT_ER R/W1CP 0h Indicates if INT pin error is detected. Bit is clear when host writes back '1'.
0h = No INT error detected
1h = INT error detected
1 OTP_CRC_ER R/W1CP 0h Indicates if OTP CRC error is detected. Bit is clear when host writes back '1'.
0h = No OTP CRC error detected
1h = OTP CRC error detected
0 VCC_UV_ER R/W1CP 0h Indicates if VCC undervoltage was detected. Bit is clear when host writes back '1'. Ignore this bit status if VCC < 2.3V.
0h = No VCC UV detected
1h = VCC UV detected
