126 / 555 page ![]() www.national.com 126 Revision 0.8 UART/IR Controller Functional Description (Continued) 4.11.1 Operational Modes This section describes the operation modes of the UART/IR Controller. Although each mode is unique, certain system resources and features are common. This discussion references several bits in the UART/IR Controller Native register set. Table 4-19 provides the bit map for the UART/IR Controller Native registers for the reader’s convenience. For full bit descriptions, refer to Sec- tion 5.12.2 on page 366. Table 4-19.
