Programming Sequence and Flow Charts
Go in I/O configuration
OUT 2Eh, 87h, 87h
Save original value
Set LDN=01h or 02h to select UART1
or UART2 Configuration Register
BIOS Level
Kernel mode driver
UART Function select:
F1[2:0]=100b;
Smart Card Reader
F2[1:0]=01b;
SCR_CLKSEL = 3.5 MHz
F2[1:0]=01b;
SCR_CLKSEL = 3.5 MHz
Set Baud rate = 9600
1. LCR[7] = 1b
2. DLL[7:0] = 0Ch
3. DLM[7:0] = 00h
4. LCR[7] = 0b
Enable FIFO: write
FCR[0] = 1b
FCR[7:6] = 00b
IF FIFO is enabled,
read IIR[7:6] = 11b
Out2 enable;
Reset SCR and generate clock;
1. MCR [3] = 1b
2. MCR[1:0] = 00b
3. MCR[1:0] = 01b
4. MCR[1:0] = 11b
Wait for smart card ATR and
smart card command
No parity; 8 data bits in width;
1 stop bit; LCR[3:0] = 0011b
