73S12xxF Software User Guide
4.1.2 External Data Memory
The 2 KB of XRAM are available at address locations 0x0000 through 0x07FF. The upper 1K bytes of
the external data memory space (from 0xFC00 to 0xFFFF) is reserved for additional special function
registers for the 73S12xxF chip and is segmented as shown in
4.1.3 Internal Data Memory
The 256 bytes of IRAM are available for use as scratch-pad RAM.
The IRAM Special Function Registers are mapped as shown in
first column (000b) are bit-addressable:
4.2
A low-level Application Programming Interface (API) is provided to control all hardware peripherals. An
application can link to the low-level API library to utilize the functions described in subsequent sections.
Before using the low-level API, an embedded application should call the API_Init() routine in the
beginning of the program as part of its initialization. As a general guideline, any feature to be included or
used in an application must first call its associated initialization routine. For example, to link the USB
module into an application, USB_Init() must first be called to initialize its associated registers for the USB
functions.
Each feature available with the 73S12xxF device has a sample application to demonstrate the library
function’s usage.
