Module builtin 

Runtime routines provided by the startup code, exposed as raw symbols.

The RST helpers use a register-based calling convention, so they are meant to be invoked from inline assembly (for example through the sym operand), not called directly. isr_noop is an ordinary parameterless routine.

Functions

call_hl^⚠

RST 0x20 indirect call helper: jp (hl), jumping to the address in HL.

isr_noop^⚠

Default interrupt handler: returns immediately.

memcpy_small^⚠

RST 0x30 small memcpy: copy C bytes from DE to HL.

memset_small^⚠

RST 0x28 small memset: fill C bytes at HL with A.
