Description

RTC Status Register

Fields

INVAL_BIT

Invalidate CPU read/write access bit.

0 (0): Time /Date Counters can be read/written. Time /Date is valid.

1 (1): Time /Date Counter values are changing or Time /Date is invalid and cannot be read or written.
WRITE_PROT_EN

Write Protect Enable status bit.

0 (0): Registers are unlocked and can be accessed.

1 (1): Registers are locked and in read-only mode.
CPU_LOW_VOLT

CPU Low Voltage Warning status bit.

0 (0): CPU in Normal Operating Voltage.

1 (1): CPU Voltage is below Normal Operating Voltage. RTC Registers in read-only mode.
RST_SRC

Reset Source bit.

0 (0): Part was reset due to Standby Mode Exit (that is when VDD is powered up and VBAT was not powered down at all).

1 (1): Part was reset due to Power-On Reset (that is Power On Reset when both VBAT and VDD are powered up).
CMP_INT

Compensation Interval bit.
WE

Write Enable bits.

2 (10): Enable Write Protection - Registers are locked.
BUS_ERR

Bus Error bit.

0 (0): Read and Write accesses are normal.

1 (1): Read or Write accesses occurred when INVAL_BIT was asserted.
CMP_DONE

Compensation Done bit.

0 (0): Compensation busy or not enabled.

1 (1): Compensation completed.
