System-Side Data Input/Output. DAT_VP is an input if OE/INT is logic 0.
DAT_VP is an output if OE/INT is logic 1. Program the function of DAT_VP
with the dat_se0 bit (bit 2 of control register 1, see Table 7).
Input Power Supply. Connect a +3V to +4.5V supply to V
GND with a 1µF capacitor. The supply range enables direct powering from
one Li+ battery.
No Connection. Not internally connected.
Charge-Pump Flying-Capacitor Negative Terminal
System-Side Data Input/Output. SE0_VM is an input if OE/INT is logic 0.
SE0_VM is an output if OE/INT is logic 1. Program the function of SE0_VM
with the dat_se0 bit (bit 2 of control register 1, see Table 7).

D+ and D- Differential Receiver Output. In receive mode (see Table 4), when
D+ is high and D- is low, RCV is high. In receive mode, when D+ is low and
D- is high, RCV is low. RCV is low in suspend mode.
Speed-Selector Input. Connect SPD to GND to select the low-speed data rate
(1.5Mbps). Connect SPD to V
Disable the SPD input by writing a 1 to spd_susp_ctl (bit 1 in special-function
register 1, see Table 14). The speed bit (bit 0 of control register 1, see Table
7) determines the maximum data rate of the MAX3301E/MAX3302E when the
SPD input is disabled.
System-Side Logic-Supply Input. Connect to the system’s logic-level power
supply, +1.65V to +3.6V. This sets the maximum output levels of the logic
outputs and the input thresholds of the logic inputs. Bypass to GND with a
0.1µF capacitor.
Active-High Suspend Input. Drive SUS low for normal USB operation. Drive
SUS high to enable suspend mode. RCV asserts low in suspend mode.
Disable the SUS input by writing a 1 to spd_susp_ctl (bit 1 in special-function
register 1, see Table 14). The suspend bit (bit 1 of control register 1, see
Table 7) determines the operating mode of the MAX3301E/MAX3302E when
the SUS input is disabled.
