WR_ONCE_DONE

When the bit WRITE_ONCE in MASTER_CONFIG (14h) is configured as 1, this bit is set to 1 when the

write operation on slave 0 has been performed and completed. Default value: 0

SLAVE3_NACK

This bit is set to 1 if Not acknowledge occurs on slave 3 communication. Default value: 0

SLAVE2_NACK

This bit is set to 1 if Not acknowledge occurs on slave 2 communication. Default value: 0

SLAVE1_NACK

This bit is set to 1 if Not acknowledge occurs on slave 1 communication. Default value: 0

SLAVE0_NACK

This bit is set to 1 if Not acknowledge occurs on slave 0 communication. Default value: 0

SENS_HUB_ENDOP

Sensor hub communication status. Default value: 0

(0: sensor hub communication not concluded;

1: sensor hub communication concluded)

TIMESTAMP0 (40h), TIMESTAMP1 (41h), TIMESTAMP2 (42h), and TIMESTAMP3

(43h)

Timestamp first data output register (R). The value is expressed as a 32-bit word and the bit resolution is 25 µs.

These registers are also accessible from ISPU at address 6940h, 6941h, 6942h, 6943h (R).
