2.1.5 VERSION Register
The VERSION register contains two read only fields that indicate the BOARD and
CPLD versions. This register will allow your software to differentiate between
production releases of the EVM and account for any variances. This register is not
expected to change often, if at all.
2.1.6 MISC Register
The MISC register is used to provide software control for miscellaneous board
functions. On theC6413/C6418 EVM, the MISC register controls how auxiliary signals
are brought out to the daughter-card connectors.
McBSP0SEL, McBSP1SEL and McBSP2SEL control the McBSP0, McBSP1 and
McBSP2 respectively. Usually these ports are used to interface ports to the on-board
AIC23 codec, the RS-232 UART driver, or SPI Serial ROM as examples. The
power-on state of these bits (both 0s) represents that situation. Setting the
corresponding bit to 1 enables the McBSP to the expansion daughter-card instead
interface.
