Read a data from PWM register in SFR Method 2 (Page Mode):
Example: Read the PWMSEV data in SFR Method 2, Page 1.
PAGESEL = 0x3h;
// Method 2, Page 1 (Page mode)
Val = PWMSEV;
// Val: Read data from PWMSEV.
The PWM Method1 and PWM Method 2 is same result.

Write data to USB Register in SFR Method 1 (Indirect Mode):
Example: Write data 0x1h to UCTRL1 Register in SFR Method 1.
PAGESEL = 0x0h;
// Method 1.
// (Refer Page1 Table of the Method 2)
USBDATA = 0x1h;
// Write data 0x01h to UCTRL1.
USBADDR = 0xFEh; // UCTRL1 indirect address: 0xFEh (Indirect mode)
Write a data to USB Register in SFR Method 2 (Page Mode):
Example: Write data 0x1h to UCTRL1 Register in SFR Method 2, Page 1.
PAGESEL = 0x3h;
// Method 2, Page 1 (Page mode)
UCTRL1 = 0x01h;
// Write data 0x01h to UCTRL1.
The USB Method1 and USB Method 2 is same result.
