// ALTERA_AVALON_LCD_16207 PERIPHERAL
//
// Provides a hardware interface that allows software to
// access the two (2) internal 8-bit registers in an Optrex
// model 16207 (or equivalent) character LCD display (the kind
// shipped with the Nios Development Kit, 2 rows x 16 columns).
//
// Because the interface to the LCD module is "not quite Avalon,"
// the hardware in this module ends-up mapping the module's
// two physical read-write registers into four Avalon-visible
// registers: Two read-only registers and two write-only registers.
// A picture is worth a thousand words:
//
// THE REGISTER MAP

// 7 6 5 4 3 2 1 0 Offset
// +-----+-----+-----+-----+-----+-----+-----+-----+
// RS = 0 | Command Register (WRITE-Only) | 0
// +-----+-----+-----+-----+-----+-----+-----+-----+
// RS = 0 | Status Register (READ -Only) | 1
// +-----+-----+-----+-----+-----+-----+-----+-----+
// RS = 1 | Data Register (WRITE-Only) | 2
// +-----+-----+-----+-----+-----+-----+-----+-----+
// RS = 1 | Data Register (READ -Only) | 3

上面是sopc_builder自身提供的Optrex 16207LCD的寄存器映射文件，我想问问的是它这样映射有什么说法没有呢 [em06][em06] |
