Hi! I am using LPC11uxx and trying to configurate UART smart card mode. When I filled register DLM value, IER also fiiled by the same value? Is it normal? If yes, why it is happens?
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) When I filled register DLM value, IER also filled by the same value?
-- Yes, their address is identical, however, the value of DLAB bit determine the writing value be valid or not.
Have a great day,
TIC
