Note: PINMUX group EMIFA/VPSS Sub-Block 2 is not shown in the above table because there is no
actual pin multiplexing in that block. But this block is still considered a "pin mux block" because it contains
some of the pins necessary for EMIFA. The pins in this block are as follows:
• EMIFA/VPSS Sub-Block 2
– EM_WAIT/(RDY/BSY)
– EM_OE
– EM_WE
3.7.3.2 Peripherals Spanning Multiple Pin Mux Blocks
Some peripherals span multiple Pin Mux Blocks. To use these peripherals, they must be selected in all of
the relevant Pin Mux Blocks. The following is the list of peripherals that span multiple Pin Mux Blocks:
• McBSP0: Six McBSP0 pins are located in the Serial Port Sub-Block 0, but the CLKS0 pin is muxed in
the Timer0 Block. To select McBSP0 pins, program PINMUX registers as follows:
– Serial Port Sub-Block 0: SPBK0 = 01
– Timer0 Block: If CLKS0 pin is desired, program TIM0BK = 10 or 11.
• UART0: The two UART0 data pins are located in the UART0 Data Block, but the two UART0 flow
control pins are located in the UART0 Flow Control Block. To select UART0, program PINMUX
registers as follows:
– UART0 Data Block: UR0BK = 1
– UART0 Flow Control Block: If flow control pins are desired, program UR0FCBK = 01.
