Description
digital ground
supply voltage (3.3 or 5.0 V)
for 5.0 V operation, this is the only pin used. Refer to
Section 10
analog ground
regulated supply voltage (3.3 V
regulator; supplies internal analog circuits; used to connect
decoupling capacitor and 1.5 k pull-up resistor on D line
Remark: Cannot be used to supply external devices. Refer
to
USB D connection (analog)
USB D connection (analog)
connection for external pull-up resistor for USB D line;
must be connected to V
connection for external bias resistor; must be connected to
ground via a 12.0 k ( 1%) resistor
selects function of pin ALE/A0 (in Split Bus mode only):
0 — ALE function (address latch enable)
1 — A0 function (address/data indicator).
Remark: Connect to V
mode.
