Subject: msp430 usci: add setIfgTx(), setIfgRx()
X-Git-Url: https://oss.titaniummirror.com/gitweb/?p=tinyos-2.x.git;a=commitdiff_plain;h=3fe8f13e05a2bcbc4a224f5a7b7f0ae45398a9b5

msp430 usci: add setIfgTx(), setIfgRx()

With upcoming support for DMA transfers with the USCI peripheral,
support for setting the IFG bits will be required.
