12.2.4.5 Transmitter Time Guard

When the transmitter time guard (TTG) feature is enabled and configured for a time value greater than 0, it allows programmable wait periods between transmissions. It can be configured in the Table 12-26 register. On each byte transfer, the transmitter enters a TTG wait state prior to sending out the stop bits. Tx Time Guard Value = TTG x Bit Time (Tbit).
