P330 Data Sheet / User Guide 19
DRAFT
Finally, it may be useful to clarify the directions associated with the Serial transmit (TX) and receive
(RX) lines. “User Serial TX” means transmitted by the P330 to the Host. “User Serial RX” means
received by the P330 from the Host. All user serial lines operate at 3.3v.
