Modifications:

• Table 1 “Ordering information”: added column “Topside mark”

• Table 2 “Ordering options” re-written: added orderable part number, packing method,

minimum order quantity; column “Topside mark” moved to Table 1

• Table 18 “Output port configuration register (address 47h)”: bit 0 symbol corrected from

“ODEND0” to “ODEN”

• Section 9.4 “Device current consumption with internal pull-up and pull-down resistors”,

second paragraph, first sentence corrected from “The pull-up or pull-down function is selected

in registers 48h and 49h, while the resistor is connected by the enable registers 46h and 47h.”

to “The pull-up or pull-down function is selected in register 44h, while the resistor is connected

by the enable register 43h.”
