Collect

MCU memory configuration:

On-chip RAM 128 bytes (00H-7FH);

The first 32 units of the on-chip RAM are the working register area (00H-1FH)

The on-chip RAM has 128 bit-addressable bits, occupying 16 cells.

The bit address number is: 00H-7FH, distributed in 20H-2FH units (P.27)

Among the 21 special function registers (SFRs) on the chip: each bit in the SFR whose address number is divisible by 8 can also be addressed bit by bit (P.27-28)

Addressable off-chip RAM 64K bytes (0000H - FFFFH)

Addressable off-chip ROM 64K bytes (0000H—FFFFH)

On-chip ROM 4K bytes (000H-FFFH)

Close collaboration with compiler developers to optimize microcontroller development

The result of the cooperation between the microcontroller development team and the compiler developers is that the generated code is more efficient and has better performance. This article describes the adjustments made to the microcontroller architecture and instruction set during the compiler development phase in or

Microcontroller Summary

There are usually two types of numbers in computers: unsigned numbers and signed numbers. Original code: positive number (highest bit 0); negative number (highest bit 1) -(2n-1-1)~+(2n-1-1) Inverse code: positive number (same as original code); negative number (sign bit remains unchanged, other bits are inverted)

Sensorless Field Oriented Control Using an 8-bit Microcontroller

Introduction Field-oriented control (FOC) is increasingly being used in consumer and industrial motors due to its higher efficiency, better dynamic response and lower torque ripple. The implementation of sensorless FOC technology using Infineon's 8-bit microcontrollers XC886 and XC888 (when outputting 15kHz PWM
