8 / 167 page  ST7LITE3 8/167 3 REGISTER & MEMORY MAP As shown in Figure 3, the MCU is capable of ad- dressing 64K bytes of memories and I/O registers. The available memory locations consist of 128 bytes of register locations, 384 bytes of RAM, 256 bytes of data EEPROM and 8 Kbytes of user pro- gram memory. The RAM space includes up to 128 bytes for the stack from 180h to 1FFh. The highest address bytes contain the user reset and interrupt vectors. The Flash memory contains two sectors (see Fig- ure 3) mapped in the upper part of the ST7 ad- dressing space so the reset and interrupt vectors are located in Sector 0 (F000h-FFFFh). The size of Flash Sector 0 and other device op- tions are configurable by Option byte. IMPORTANT: Memory locations marked as “Re- served” must never be accessed. Accessing a re- seved area can have unpredictable effects on the device. Figure 3. Memory Map 1. DEE0h, DEE1h, DEE2h and DEE3h addresses are located in a reserved area but are special bytes containing also the RC calibration values which are read-accessible only in user mode. If all the EEPROM data or Flash space (including the RC calibration values locations) has been erased (after the read out protection removal), then the RC calibration values can still be obtained through these addresses. 0000h RAM Flash Memory (8K) Interrupt & Reset Vectors HW Registers 0080h 007Fh 0FFFh (see Table 2) 1000h 10FFh FFE0h FFFFh (see Table 5) 0200h Reserved 01FFh Short Addressing RAM (zero page) 128 Bytes Stack 0180h 01FFh 0080h 00FFh (384 Bytes) E000h 1100h DFFFh Reserved FFDFh 16-bit Addressing RAM 0100h 017Fh 1 Kbyte 7 Kbytes SECTOR 1 SECTOR 0 8K FLASH FFFFh FC00h FBFFh E000h PROGRAM MEMORY Data EEPROM (256 Bytes) DEE0h RCCRH1 RCCRL1 see section 7.1 on page 22 and Note 1) DEE1h DEE2h RCCRH0 RCCRL0 DEE3h DEE4h 1 |
