ation, suspend mode, interrupt shutdown, and shut-
down. For the ESD structures to work correctly, connect
a 1µF or greater capacitor from TRM to GND and from
V
ways; the D+, D-, ID_IN, and V
characterized for protection to the following limits:
Note: sess_end value at power-up is dependent on the voltage at V

Set to 0 for normal operation. Set to 1 to enable shutdown mode. Only the I
interface remains active in shutdown.
Set to 0 to set INT and OE/INT as open-drain outputs. Set to 1 to set INT and
OE/INT as push-pull outputs.

Set to 0 to transfer data from DAT_VP and SE0_VM to D+ and D-, respectively.
DAT_VP and SE0_VM are always inputs when this bit is 0. Set to 1 to control the
direction of data transfer with OE/INT.
Set to 0 to transfer data from SE0_VM to D-. Set to 1 to transfer data from D- to
SE0_VM. Ensure that gp_en = 1, dat_se0 = 1, uart_en = 0, and OE/INT = low to
activate this function.
Set to 0 to transfer data from DAT_VP to D+. Set to 1 to transfer data from D+ to
DAT_VP. Ensure that gp_en = 1, dat_se0 = 1, uart_en = 0, and OE/INT = low to
activate this function.
Set to 0 to use cr_int as the interrupt source for bit 7 of the interrupt source
register. Set to 1 to use sess_end as the interrupt source for bit 7 of the interrupt
source register (see Table 10).
Session end comparator status (read only). Sess_end = 0 when V

Set to 0 to disable general-purpose buffer mode. Set to 1 to enable general-
purpose buffer mode.
