DEVICE CONFIGURATIONS (CONTINUED)<br />

peripheral selection/device configurations via the DEVCFG control register<br />

SPRS294A − OCTOBER 2005 − REVISED NOVEMBER 2005<br />

The device configuration register (DEVCFG) allows the user to control the pin availability of the McBSP0,<br />

McBSP1, McASP0, I2C1, and Timer peripherals. The DEVCFG register also offers the user control of the EMIF<br />

input clock source and the timer output pins. For more detailed information on the DEVCFG register control bits,<br />

see Table 20 and Table 21.<br />

0 MCBSP1DIS<br />

EMIF input clock source bit.<br />

Determines which clock signal is used as the EMIF input clock.<br />

0 = SYSCLK3 (from the clock generator) is the EMIF input clock source (default)<br />

1 = ECLKIN external pin is the EMIF input clock source<br />

Timer 1 output (TOUT1) pin function select bit.<br />

Selects the pin function of the TOUT1/AXR0[4] external pin independent of the rest of the peripheral<br />

selection bits in the DEVCFG register.<br />

0 = The pin functions as a Timer 1 output (TOUT1) pin (default)<br />

1 = The pin functions as the McASP0 transmit/receive data pin 4 (AXR0[4]).<br />

The Timer 1 module is still active.<br />

Timer 0 output (TOUT0) pin function select bit.<br />

Selects the pin function of the TOUT0/AXR0[2] external pin independent of the rest of the peripheral<br />

selection bits in the DEVCFG register.<br />

0 = The pin functions as a Timer 0 output (TOUT0) pin (default)<br />

1 = The pin functions as the McASP0 transmit/receive data pin 2 (AXR0[2]).<br />

The Timer 0 module is still active.<br />

Multichannel Buffered Serial Port 0 (McBSP0) disable bit.<br />

Selects whether McBSP0 or the McASP0 multiplexed peripheral pins are enabled or disabled.<br />

0 = McBSP0 peripheral pins are enabled, McASP0 peripheral pins (AHCLKR0, ACLKR0,<br />

ACLKX0, AXR0[0], AXR0[1], AFSR0, and AFSX0) are disabled (default).<br />

[If the McASP0 data pins are available, the McASP0 peripheral is functional for DIT<br />

mode only.]<br />

1 = McBSP0 peripheral pins are disabled, McASP0 peripheral pins (AHCLKR0, ACLKR0,<br />

ACLKX0, AXR0[0], AXR0[1], AFSR0, and AFSX0) are enabled.<br />

Multichannel Buffered Serial Port 1 (McBSP1) disable bit.<br />

Selects whether McBSP1 or I2C1 and McASP0 multiplexed peripheral pins are enabled or disabled.<br />

0 = McBSP1 peripheral pins are enabled, I2C1 peripheral pins (SCL1 and SDA1) and McASP0<br />

peripheral pins (AXR0[7:5] and AMUTE0) are disabled (default)<br />

1 = McBSP1 peripheral pins are disabled, I2C1 peripheral pins (SCL1 and SDA1) and McASP0<br />

peripheral pins (AXR0[7:5] and AMUTE0) are enabled.<br />
