About ADSP 2181 Software UART (bug fixed)
Started by Jaime Andres Aranguren Cardona ●July 9, 2001
Hi, people.
There is a small bug fix to the software UART I sent to some of you. In the
UART.asm file change
// Enable and set up SPORT1 as FI and FO pin ax0 =
b#0000100000000000; ay0 = Sys_Crtl_Reg; ar = ax0 or ay0;
// Enable SPORT1 ay0 =
b#1111101111111111; ar = ar and ay0; // Set
up SPORT1 as FI/O
for
// Enable and set up SPORT1 as FI and FO pin ax0 =
b#0000100000000000; ay0 = dm(Sys_Crtl_Reg); ar = ax0 or
ay0; // Enable SPORT1 ay0 =
b#1111101111111111; ar = ar and ay0; // Set
up SPORT1 as FI/O dm(Sys_Ctrl_Reg) = ar;
In order to effectively change the "Sys_Ctrl_Reg" as desired
MfG (Mit freundlichen Grse),
