Fig. 8– Mapping address of FLASH blocks

FLASH erase/write operation is manipulated by calling system function. The system function is pre-stored

in the ROM of 0000H~0FFFH. In order to make sure the correct of FLASH’s content, we recommend user to

check 2.2V low voltage detecting flag LVDCtrl[2] before manipulate write or erase operation to FLASH. If

XRAM

SC51D01Fxx series integrates 4K bytes RAM as external data memory XRAM, the address space is

0000H~0FFFH.

XRAM can be accessed by external movement instructions “MOVX A, @DPTR”.“MOVX @DPTR, A”.“MOVX A,

@Ri” and “MOVX @Ri, A” . If using the latter two instructions, only can access the address space 0000H~00FFH.

Special attention should be paid that: 0100H~01EDH of XRAM is occupied by the system, can not be changed

by the system; 0D00H~0DFFH is receiving buffer of code sampling module(code sampling buffer for short).

Code Sampling Module

[Brief]

Code sampling module is used to collect the infrared signal from other remote control which can

implement the self-learning function. When select inner infrared amplifier function, you only connect an

infrared receiving diode and 1nF capacitor between CYIN pin and GND(refer to typical application circuit) to

realize the sampling of the infrared signal.
