Table 6–29. Functional Multiplexing Control 2 Register (FUNC_MUX_CTRL_2)

Reserved. These bits must always be written as 0.

This 6-bit field can be used to control the DMA re-

quests observability mux.

When a 6-bit value is written in this field, the corre-

sponding interrupt signal is output on the

UART3.RX pin for visibility.

Legal values are from 0 to 50. 0 is the functional

mode, values between 1 and 50 are for

observability mode.

0: Default; for i = 1 to 19: observability, pin

UART3.RX <= DSP DMA request(i), output; for i =

20 to 50: observability, pin UART3.RX <= system

DMA request(i–20), output

This 7-bit field can be used to control the interrupt

observability mux.

When a 7-bit value is written in this field, the corre-

sponding interrupt signal is output on the

UART3.TX pin for visibility.

Legal values are from 0 to 101. 0 is the functional

mode; values between 1 and 101 are for

observability mode.

0: Default; for i in 1 to 16: observability, UART3.TX

pin <= DSP level2 interrupt(i–1);

for i in 17 to 37: observability, UART3.TX pin <=

DSP level1 interrupt(i–17);

for i in 38 to 69: observability, UART3.TX pin <=

MPU level1 interrupt(i–38);

for i in 70 to 101: observability, UART3.TX pin <=

MPU level2 interrupt(i–70);

Reserved. These bits must always be written as 0.

At reset, the OMAP5910 device configuration registers are software compat-

ible with previous prototype devices. Writing an 0x0000EAEFh to the compati-

bility mode control 0 register (COMP_MODE_CTRL_0) enables the new

functional multiplexing registers found at offset 0x10h and above.
