Programming the

TH6503

(continued)

Write next Device Data to TH6503

If IN FIFO data has to be sent to the USB host the microcontroller must wait until the corresponding IN

DONE bit is set (IN FIFO is empty). Then the microcontroller can store the next data in the IN FIFO.

Write Adr/CntInRegister

Write Internal Register

Write next Control

Byte(s) to

IN FIFO 0

Write next Device

Data to

IN FIFO 1 or 2

SIN=1

output first bit on SDI

generating a rising edge

on SCK to latch bit by

bridge

more bits to write ?

generating a falling edge on

Yes SCK and output the next bit

on SDI

No

End of IN Transfer

SIN=0 and SCK=0
