Load Byte Unsigned (ldbu)

Syntax

ldbu $d_reg, address

Description

Load Byte Unsigned loads the least significant byte of the destination register with the contents of the byte specified by the effective address. Because the loaded byte is an unsigned value, the other bytes of the destination register are cleared to zeros.

Note   The assembler destroys the contents of temporary registers $at and $t9 for this instruction unless the .arch directive or the /arch command-line option causes the assembler to generate a single machine instruction in response to the ldbu command.
