43 DRVPWRVLD
(DA2)
I Input Device presence detect. (See “DRVPWRVLD” on
page 13). Configurable logical polarity is controlled by
EEPROM address 0x08. This pin must be pulled HIGH
if functionality is not utilized.
Alternate function. Input when the EEPROM configu-
ration byte 8 has bit 7 set to one. The input value is
reported through EP1IN (byte 0, bit 0).
