Question about MMA9555L data sheet

"19.13 Configure output interrupt: Activity change on GPIO6

This command writes two bytes of the configuration variable to the GPIO application (APP_ID=0x03), starting at byte offset 0. This causes the GPIO application to copy the pedometer's ACTCHG status bit to GPIO6 after every new accelerometer sample. The host processor can trigger an interrupt on rising edges of this pin to receive notification when the activity level changes.

03 20 00 02 15 04

19 20 01 01 (AB & 6F)"

Question about the above command,what does the '(AB & 6F)' mean?

Hi,

As the MMA9555L was discontinued in 2018, there is a very limited support we can offer for this part.

Please expect some delay in responding.

Best regards,

Tomas
