Convert the hexadecimal numbers on the left side of the HCS12 memory map to decimal and binary
Expert Answer
Memory Map of HCS12:
| Memory Map | Internal Registers | EEPROM | RAM | Flash(non banked i.e not selected by registers) | Flash EEPROM(banked i.e selected by registers) | Flash(non banked) |
| Memory Map addresses | 0 to 3FF | 400 to FFF | 1000 to 3FFF | 4000 to 7FFF | 8000 to BFFF | C000 to FFFF |
| Address range in binary | (0000 0000 0000 0000)2to (0000 0011 1111 1111)2 | (0000 0100 0000 0000)2to (0000 1111 1111 1111)2 | (0001 0000 0000 0000)2to (0011 1111 1111 1111)2 | (0100 0000 0000 0000)2 to (0111 1111 1111 1111)2 | (1000 0000 0000 0000)2 to (1011 1111 1111 1111)2 | (1100 0000 0000 0000)2 to (1111 1111 1111 1111)2 |
| Address range in decimal | 0 to 1023 | 1024 to 4095 | 4096 to 16383 | 16384 to 32767 | 32768 to 49151 | 49152 to 65535 |
Method of converting hexadecimal to binary:
- Consider a hexadecimal digit equivalent to 4 binary digits(or 4 bit binary digit).
- Therefore each hexadecimal number is formed by grouping a 4 bits binary digit.
- For example 3FFF in hex = 0011 1111 1111 1111 in binary.
Method of converting hexadecimal to decimal:
- After converting hex digits into binary, it becomes easier to convert it from binary to decimal.
- For example 3FF in hex = 0011 1111 1111 in binary = 1023 in decimal
