MUX_SEL
0xC9
Selection of peripheral reuse.
.7 1 = CAN interface leads to P 0.2 and P 0.3; 0 = CAN interface is not lead out, and it works
as an IO port.
.6 1 = UART2 interface leads to P 0.4 and P 0.5; 0 = UART2 interface is not lead out, and it works
as an IO port.
.5 1 = UART3 interface leads to P 0.6 and P 0.7; 0 = UART3 interface is not lead out, and it works
as an IO port.
.4-.2 Reserved;
.1 WDT control. 1=open; 0=close;
.0 WDT feed dog. 1=feed the dog one time(The WDT count becomes zero, and the watchdog's
overflowing time is 1 );
PORTDRV

Driver capability configuration of IO port output mode, 0x00 = 4mA 0x01=8mA(recommended
values) 0x02=16mA 0x03=32mA

0x0013
IE1(TCON.3)
IEN0.2
IE1 is cleared automatically when interrupt response,
corresponding to P3.1.
IT1 (TCON.2) = low level trigger interrupt, IT1 = 1 jump
down edge trigger interrupt.
