Table 15, Per-Baud rate ACK timeout values.
Default CRC Checking: Enabled (0x01)
Set to 0x01 to enable receiver CRC-16 validation, or 0x00 to disable. If this register is enabled (0x01), an
invalid packet will not be sent to the UART interface for transmission; it will be discarded. The default CRC
mode setting is enabled.
Default UART Minimum Transmission Unit: 64
This register determines the UART buffer level that will trigger the transmission of a packet. This register
works in conjunction with the
code logical arrangement is:
if (UART_incoming_buffer_size >= regUARTMTU) or (UART_last_char_received_timer >
regTXTO) then SendPacket()
The minimum value is 1 and the maximum value is 192. The default value for this register is 64, which
provides a good mix of throughput and latency. At maximum data rate, a value of 128 will optimize
throughput. This register does not guarantee a particular transmission unit size; rather, it specifies the
minimum desired size. If there is not enough time left in a hop, for instance, the packet engine will send as
many characters as it can to fill the current hop, and send the remaining characters in the next hop.
