AS39513 − Detailed Description

OVWRT – Measurement overwrite flag.

0 = No measurements have been overwritten.

1 = At least one measurement has been overwritten.

EEFULL – The EEPROM is full.

0 = More measurements can be logged.

1 = At least one measurement was not logged due to a lack of

EEPROM space.

ACTIVE – Controller state.

0 = Controller is in the IDLE or WAIT modes.

1 = Controller is in the ACTIVE mode.

MEASPTR[11:0] – Measurement pointer. The EEPROM value is

the pointer value at the end of a logging operation. The register

copy of this measurement pointer will also be updated with

each EEPROM write during logging so that it always points to

the next logging location. The upper 10 bits of this 12-bit value

is the address in the Application and Measurement EEPROM

area to which to write. The two LSB’s represent the current bit

position. The logging values are all 2, 6, 8, or 10-bit values, so

they will always fall on one of the four two-bit boundaries in a

byte.

WAKEMD – Wakeup mode.

0 = The AS39513 always reinitializes after a power-up reset but

the MEASCNT and MEASPTR values in EEPROM from any

previous data logging will be retained as long as the chip stays

in idle mode.

1 = The AS39513 will skip to ACTIVE mode after a power-up reset

if ACTIVE = 1.
