output to provide ramp up time for RF/IF circuits.

are modulated after last chip of valid data to provide
ramp down time for RF/IF circuits.
21. Delay from TXC to inactive edge of TXPE to prevent next TXC.
Because TXPE asynchronouslystopsTXC, TXPE going inactive
within 40ns of TXC will cause TXC minimum hi time to be less
than 40ns.
