dm6437管脚复用
1. Tmer0
说明:仅仅是有Timer0 Block决定
配置:
2. Timer1
说明:仅仅是由Timer1 Block决定的
配置:
3. UART0
说明:UART0的配置是由2个Blocks决定的分别是
UART0 Data Block, and UART0 Flow Control Block
配置:
4. UART1
说明:UART1不同于UART0,仅仅支持数据pins而不支持溢出控制pins,所以由仅仅Timer1 Block决定
配置:
5. PWM0
说明:仅仅是由UART0 Flow Control Block决定
配置:
6. PWM1
说明:仅仅是由PWM1 Block决定的
配置:
7. PWM2
说明:仅仅是由CLKOUT Block决定的
配置:
8. CLKOUT0
说明:仅仅是由CLKOUT Block决定的
配置:
9. PCI(巨复杂)
说明:PCI是由
Host Block
EMIFA/VPSS Block Sub-Block 0 and Sub-Block 3
PCI Data Block
GPIO Block 决定
配置:参见P116页
Note:
The EMIFA/VPSS Block is divided into multiple sub-blocks for ultimate flexibility in pin multiplexing to accommodate a wide variety of applications:
1. Sub-Block 0: multiplexedbetween VPFE, EMIFA data/address/control pins, PCI, andGPIO.
2. mSub-Block 1: multiplexedbetween VPBE, EMIFA data/address/control pins, andGPIO.
3. Sub-Block 2: no multiplexing. EMIFA control pinsEM_WAIT/(RDY/BSY), EM_OE,EM_WE.
4. Sub-Block 3: multiplexedbetween EMIFA address pins EM_A[12:6], PCI, and GPIO.
10.McBSP0
说明:Serial PortSub-Block0, and Timer0 Block
配置:
11.McBSP1
说明:Serial Port Sub-Block1, and Timer0 Block
配置同上
