Introduction: Notes on the description of SFR (Special Function Register) under this specifica-
tion
An SFR (Special Function Register) is a control register for periperal circuits (IP).
The SFR addressses of IPs are described in the chapter on memory map, and the details of SFR are given in the
chapter of each IP.
Definition of SFR used in this specification is in accordance with the following rules.
a.
SFR table of each IP as an example
・
SFR tables in each chapter of IP provides register names, addresses and brief descriptions.
・
All registers have a 32-bit unique address and the addresses of the registers are defined as follows, with
some exceptions: "Base address + (Unique) address"
Base Address = 0x0000_0000
Register name
Control register
SAMCR
Address(Base+)
0x0004
0x000C
Note:
SAMCR register address is 32 bits wide from the address 0x0000_0004 (Base Address(0x00000000) +
unique address (0x0004)).
The register shown above is an example for explanation purpose and not for demonstration purpose. This
register does not exist in this microcontroller.
Note:
b. SFR(register)
・
Each register basically consists of a 32-bit register (some exceptions).
・
The description of each register provides bits, bit symbols, types, initial values after reset and functions.

d. Register descriptoption
Registers are described as shown below.
・
Register name <Bit Symbol>
Exmaple: SAMCR<MODE>="000" or SAMCR<MODE[2:0]>="000"
<MODE[2:0]> indicates bit 2 to bit 0 in bit symbol mode (3bit width).
・
Register name [Bit]
Example: SAMCR[9:7]="000"
It indicates bit 9 to bit 7 of the register SAMCR (32 bit width).
