prodStringByte[n]

RO/RW

Product string byte N. These registers provide the string values returned

for string index 2 when prodStringLen is greater than 0. The number of

bytes returned in the string is equal to prodStringLen.

The programmed data should be in UNICODE UTF-16LE encodings as

defined by The Unicode Standard, Worldwide Character Encoding,

stsOutputEn

RO/RW

Status output enable. This bit enables the HS, HS_SUSPEND, SS, and

SS_SUSPEND outputs..

0 = HS, HS_SUSPEND, SS, and SS_SUSPEND outputs are

disabled and tri-stated.

1 = HS, HS_SUSPEND, SS, and SS_SUSPEND outputs are

enabled.

This field may be over-written by EEPROM contents or by an SMBus

Host.

3:1

pwronTime

Power On Delay Time. When OTP ROM pwronTime field is all zero , this

field sets the delay time from the removal disable of PWRCTL to the

enable of PWRCTL when transitioning battery charging modes. For

example, when disabling the power on a transition from a custom

charging mode to Dedicated Charging Port Mode. The nominal timing is

defined as follows:

TPWRON_EN = (pwronTime + 1) x 200 ms

(1)

This field may be over-written by EEPROM contents or by an SMBus

host.

usb3spreadDis

USB3 Spread Spectrum Disable. This bit allows firmware to disable the

spread spectrum function of the USB3 phy PLL.
