How to write:
Bring CS high
Use SCLK and IO to clock in the 23 octets
Bring CS low
Refer to the figure in the next section, “Writing to n
registers having incremental addresses”.
Writing to n Registers Having Incremental Addresses
In addition to entering all bytes, it is also possible to enter
a set of n bytes, starting from address i = “A6, A5, … A0”.
Typical example: Clock in a new set of frequency dividers
(i.e. change the RF frequency). “Incremental addresses”.
Registers to be written are located in i, i+1, i+2.
What to write:
Field
Comments
Address:
7 bit = A6, A5, …A0 (A6 = msb. A0 = lsb) (address of first byte to
write to)
R/W bit:
“0” for writing
Values:
n* 8 bits =
D7, D6, …D0 (D7 = msb, D0 = lsb) (written to control reg. with
address ”i”)
D7, D6, …D0 (D7 = msb, D0 = lsb) (written to control reg. with
address ”i+1”)
D7, D6, …D0 (D7 = msb, D0 = lsb) (written to control reg. with
address ”i+n-1”)
Table 5. “Address” and “R/W bit” together make 1 octet.
In addition, n octets with programming bits are entered.
Totally. 1 +n octets are clocked into the MICRF620.
How to write:
Bring CS high
Use SCLK and IO to clock in the 1 + n octets
Bring CS low
In Figure 1, IO is changed at positive edges of SCLK. The
MICRF620 samples the IO line at negative edges. The
value of the R/W bits is always “0” for writing.

Reading from the Control Registers in MICRF620
The “read-sequence” is:
1. Enter address and R/W bit
2. Change direction of IO line
3. Read out a number of octets and change IO
direction back again.
It is possible to read all, 1 or n registers. The address to
read from (or the first address to read from) can be any
valid address (0-22). Reading is not destructive, i.e. values
are not changed. The IO line is output from the MICRF620
(input to user) for a part of the read-sequence. Refer to
procedure description below.
A read-sequence is described for reading n registers,
where n is number 1-23.

Figure 3. How to read from many Control Registers
In Figure 3, 1 register is read. The address is A6, A5, …
A0. A6 = msb. The data read out is D7, D6, …D0. The
value of the R/W bit is always “1” for reading.
SCLK and IO together form a serial interface. SCLK is
applied externally for reading as well as for writing.
Bring CS active
Enter address to read from (or the first address to
read from) (7 bits) and
The R/W bit = 1 to enable reading
Make the IO line an input to the user (set pin in
tristate)
Read n octets. The first rising edge of SCLK will
set the IO as an output from the MICRF620.
MICRF will change the IO line at positive edges.
The user should read the IO line at the negative
edges.
Make the IO line an output from the user again.
