8. Programmer’s guide
SC68C752B_4
Product data sheet
The base set of registers that is used during high-speed data transfer have a
straightforward access method. The extended function registers require special access
bits to be decoded along with the address lines. The following guide will help with
programming these registers. Note that the descriptions below are for individual register
access. Some streamlining through interleaving can be obtained when programming all
the registers.
Table 24.
Command
Set baud rate to VALUE1, VALUE2
Set Xoff1, Xon1 to VALUE1, VALUE2
Set Xoff2, Xon2 to VALUE1, VALUE2
Set software flow control mode to VALUE
Set flow control threshold to VALUE
