Device ID

Bits [7:5] = Chip ID

01h = PI5USB30216C

Bits [4:3] = Version ID

00h = Product version

Bits [2:0] = Vendor ID(Pericom)

00h = Pericom

Control

Bit 7 = Powersaving

0 = Enable/Active state

1 = Disable and low power state

In Disable and low power state, all outputs of PI5USB30216C, with

the exception of CC1 and CC2 pins, are in High-Z State. CC1 and

CC2 pins are pulled low with resistor Rd.

Bits [6] = Dual role 2 Try.SRC or Try.SNK setting

0 = Enable Try.SRC supported

1 = Enable Try.SNK supported

Bits [5] = Accessory Detection in Device Mode

0 = Disable

1 = Enable

Bits [4:3] = Charging current mode

System can set the charging current mode when port is a host or dual role

acting as host. These bits are ignored when port is a device or dual role

acting as device.

00 = Default current mode

01 = Medium current mode (1.5A)

10 = High current mode (3A)

Bits [2:1] = 00h (POR value)

System can set the role of the port.

00 = Device (SNK)

01 = Host (SRC)

10 = Dual Role (DRP)

11 = Dual Role 2 (DRP) where Try.SRC or Try.SNK is supported

Bit 0 = Interrupt Mask

INTB pin is used to acknowledge system if there is any interrupt events

triggered. When this bit is set to 0, INTB pin is pulled low when an

interrupt

event occur. When this bit is set to 1, INTB pin ignores all interrupt and

remain High-Z.

0 = Do not mask interrupt

1 = Mask interrupt

Interrupt

Bits [7:2] = Reserved. Read all 0’s.

Bit 1 = Detach event

When this bit is set to 1, it indicates the unplug action. The port changes

from attached state (Attached.SNK, Attached.SRC, AudioAccessory or

DebugAccessory state) to unattached state.

Bit 0 = Attach event

When this bit is set to 1, it indicates the plug action. The port changes

from unattached state to attached state.
