65 / 257 page  3.0 Device Architecture and Configuration (Continued) Revision 1.2 65 www.national.com 3.11 SERIAL PORT 1 CONFIGURATION 3.11.1 General Description Serial Port 1 provides UART functionality by supporting serial data communication with remote peripheral device or modem. The functional blocks can function as a standard 16450 or 16550 or as an Extended UART. Serial Port 1 includes the same register banks and runtime registers as Serial Port 2 (see Section 10.3 on page 225). All the registers are VDD powered. 3.11.2 Logical Device 3 (SP1) Configuration Table 20 lists the configuration registers that affect Serial Port 1. Only the last register (F0h) is described here. See Section 3.2.3 on page 40 for descriptions of the other configuration registers. All these registers are VDD powered. Table 20. Serial Port 1 Configuration Registers Index Configuration Register or Action Type Power Well Reset 30h Activate (see Section 3.3.1 on page 43). R/W VDD 00h 60h Base Address MSB register. Bits 7-3 (for A15-11) are read only, 00000b. R/W VDD 03h 61h Base Address LSB register. Bit 2-0 (for A2-0) are read only, 000b. R/W VDD F8h 70h Interrupt Number and Wake-Up on IRQ Enable register. R/W VDD 04h 71h Interrupt Type. Bit 1 is R/W; other bits are read only. R/W VDD 03h 74h Report no DMA Assignment. RO VDD 04h 75h Report no DMA Assignment. RO VDD 04h F0h Serial Port 1 Configuration register. R/W VDD 02h |
