HAL Overview

1.2 HAL Overview
What the CSL HAL Offers:
1-4
The hardware abstraction layer, or HAL, is a set of constants and macros that
fully describes the peripheral registers by way of symbols. It is capable of hid-
ing subtle differences between devices such as bit-fields changing size or
position within a register. In addition, the HAL can substitute a NULL register
in the case where a register is supported on one device but not another. The
whole purpose of the HAL is to provide the service layer a symbolic interface
into the hardware. It is not intended as a user interface or API. This is explained
further in section 1.3 , Service Layer Overview .
