Version Register - Spectrum Digital TMS320VC5509A EVM PLUS Technical Reference

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 5509A EVM PLUS 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 the 5509A EVM PLUS, the MISC register controls how auxiliary signals
are brought out to the daughter-card connectors.
The TIN0 bit is used to select whether the DSP's TIN0 (timer) signal is connected to the
peripheral expansion connector as inputs or outputs. The expansion connector has
separate pins for inputs and outputs so each signal must be routed to one of two
physical pins. A 0 indicates that the signal should be connected to the input pin on the
expansion connector. A 1 indicates that it should be connected to the output pin.
