Overview ¶
Package reg provides primitives for retrieving and modifying hardware registers.
This package is only meant to be used with `GOOS=tamago` as supported by the TamaGo framework for bare metal Go on ARM/RISC-V SoCs, see https://github.com/usbarmory/tamago.

Functions ¶
func Wait ¶
Wait waits for a specific register bit to match a value. This function cannot be used before runtime initialization with `GOOS=tamago`.
func Wait16 ¶
Wait16 waits for a specific register bit to match a value. This function cannot be used before runtime initialization with `GOOS=tamago`.
func WaitFor ¶
WaitFor waits, until a timeout expires, for a specific register bit to match a value. The return boolean indicates whether the wait condition was checked (true) or if it timed out (false). This function cannot be used before runtime initialization.
func WaitFor16 ¶
WaitFor16 waits, until a timeout expires, for a specific register bit to match a value. The return boolean indicates whether the wait condition was checked (true) or if it timed out (false). This function cannot be used before runtime initialization with `GOOS=tamago`.
func WaitSignal ¶
WaitSignal waits, until a channel is closed, for a specific register bit to match a value. The return boolean indicates whether the wait condition was checked (true) or cancelled (false). This function cannot be used before runtime initialization.
func WriteBack16 ¶
func WriteBack16(addr uint32)
