206 / 239 page  9.0 Legacy Functional Blocks (Continued) www.national.com 206 Revision1.1 9.5 SERIAL PORT 2 (SP2) WITH INFRARED 9.5.1 General Description This functional block (SP2) provides advanced, versatile serial communications features with IR capabilities. It supports four modes of operation: UART, Sharp-IR, IrDA 1.0 SIR (hereafter SIR) and Consumer Electronic IR (also called TV Remote or Consumer remote control, hereafter CEIR). In UART mode, the Serial Port can function in 16450-Compatible mode, 16550- Compatible mode, or Extended mode. Existing 16550-based legacy software is completely and transparently supported. Organization and specific fallback mech- anisms switch the Serial Port to 16550-Compatible mode on reset, or when initialized by 16550 software. 9.5.2 UART Register Bank Overview Eight register banks, each containing eight registers, control Serial Port operation. All registers use the same 8-byte address space to indicate offsets 00h through 07h. The active bank must be selected by the software. The register bank organization enables access to the banks as required for activation of all module modes, while maintaining transparent compatibility with 16450 or 16550 software. The Bank Selection register (BSR) selects the active bank and is common to all banks. See Figure 40. Therefore, each bank defines seven new registers. Table 91.
