Eight register banks are provided to control the operation of the UIR module. These banks are mapped into the same address
range, and only the selected bank is directly accessible by the software. The address range spans 8 byte locations. The BSR
register is used to select the bank and is common to all banks. Therefore, each bank defines seven new registers. The register
banks can be divided into two sets. Banks 0-3 are used to control both UART and infrared modes of operation; banks 4-7 are
used to control and configure the infrared modes only. The register bank main functions are listed in Table 3-1. Descriptions of
the various registers are given in the following sections.
