PINMUX1 Register Description
TMS320DM6443
Digital Media System-on-Chip
SPRS282E–DECEMBER 2005–REVISED MARCH 2007
The PINMUX0 pin multiplexing register controls which peripheral is given ownership over shared pins
among EMAC, LCD, RGB888, RGB666, ATA, VLYNQ, EMIFA, HPI, and GPIO peripherals. The register
format is shown in
Figure 3-7
and bit field descriptions are given in
Table 3-14
. More details on the
PINMUX0 pin muxing fields are given in
Section 3.5.6
. A value of "1" enables the secondary or tertiary pin
function.

For proper DM6443 device operation,
always
write a value of '0' to RSV bits 30, 29, 27, and 26.

Description
Enable EMAC and MDIO function on default GPIO3V[0:16] pins.
Enable HPI module pins. Default value is derived from BTSEL[1:0] configuration inputs. HPIEN is 1 when the
BTSEL[1:0] = 10 for non-secure devices only. HPIEN default state is always 0 for secure divices.
Enable LCD_FIELD function on default GPIO[3] pin
Enable LCD_OE function on default GPIO[0] pin
Enable VPBE RGB888 function on default GPIO[2:6, 46:47] pins
Enable VPBE RGB666 function on default GPIO[46:47] pins
Enable ATA function on default EMIFA and GPIO[52:53] pins and shared UART1 pins
Enable HDDIR function on default GPIO[42] pin
Enable VLYNQ function on default GPIO[9,10:17] pins
Enable VLYNQ SCRUN function on default GPIO[9] pin
VLYNQ data width selection. This expands the VLYNQ TXD[0:3] and RXD[0:3] functions on default GPIO[10:17]
pins.
Enable EMIFA EM_CS5 function on GPIO[8]
Enable EMIFA EM_CS4 function on GPIO[9]
EMIFA address width selection. Default value is latched at reset from AEAW[4:0] configuration input pins. This
enables EMIF address function on default GPIO[10:28] pins.

The PINMUX1 pin multiplexing register controls which peripheral is given ownership over shared pins
among Timer, PLL, ASP, SPI, I2C, PWM, and UART peripherals. The register format is shown in
Figure 3-8
and bit field descriptions are given in
Table 3-15
. More details on the PINMUX1 pin muxing
fields are given in
Section 3.5.6
. A value of "1" enables the secondary or tertiary pin function.
