Value in units of 2 ms.
Depending on the number of embedded functions configured, the value ranges from 03H to 05H or
from 02H to 04H (downstream port 2 disabled).
Remark: Downstream port 2 can be disabled by connecting both D and D to V
functions are configured via the USBCONA register (see
Default value (08H): ports 1 and 2 removable, port 3 non-removable. The value can be 08H, 18H or
38H depending on the configured number of embedded functions (1, 2 or 3). When downstream
port 2 is disabled, the possible values are 4CH, 0CH or 1CH (1, 2 or 3 embedded functions).
Unicode encoded string.
X represents the hardware setting DEVNAME (4 bits), which specifies the final digit (X) in the device
name string “ISP113X”. The Unicode representation of this digit is “0000.0000.0011.DEVNAME”.
