Writing to the Control Registers in MICRF610
Writing: A number of octets are entered into MICRF610,
followed by a load-signal to activate the new setting.
Making these events is referred to as a “write sequence.” It
is possible to update all, 1, or n control registers in a write
sequence. The address to write to (or the first address to
write to) can be any valid address (0-21). The IO line is
always an input to the MICRF610 (output from user) when
writing.
What to write:
The address of the control register to write to (or if
more than 1 control register should be written to,
the address of the 1
st control register to write to).
A bit to enable reading or writing of the control
registers. This bit is called the R/W bit.
The values to write into the control register(s).
Field
Comments
Address:
A 7-bit field, ranging from 0 to 21. MSB is written first.
R/W bit:
A 1-bit field, = “0” for writing
Values:
A number of octets (1-22 octets). MSB in every octet is written
first. The first octet is written to the control register with the
specified address (=”Address”). The next octet (if there is one) is
written to the control register with address = “Address + 1” and so
on.
Table 2. Writing to the Control Registers
How to write:
Bring CS active to start a write sequence. The active state
of the CS line is “high.” Use the SCLK/IO serial interface to
clock “Address” and “R/W” bit and “Values” into the
MICRF610. MICRF610 will sample the IO line at negative
edges of SCLK. Make sure to change the state of the IO
line before the negative edge. Refer to figures below.
Bring CS inactive to make an internal load-signal and
complete the write-sequence.
The two different ways to “program the chip” are:
Write to a number of control registers (0-22) when
the registers have incremental addresses (write to
1, all or n registers)
Write to a number of control registers when the
registers have non-incremental addresses.
Writing to a Single Register
Writing to a control register with address “A6. A5, …A0” is
described here. During operation, writing to 1 register is
sufficient to change the way the transceiver works. Typical
example: Change from receive mode to power-down.
Field
Comments
Address:
7 bit = A6, A5, …A0 (A6 = msb. A0 = lsb)
R/W bit:
“0” for writing
Values:
8 bits = D7, D6, …D0 (D7 = msb, D0 = lsb)
Table 3. “Address” and “R/W bit” together make 1 octet.
In addition, 1 octet with programming bits is entered. Totally, 2
octets are clocked into the MICRF610.
How to write:
Bring CS high
Use SCLK and IO to clock in the 2 octets
Bring CS low

Figure 1. How to write to a single Control Register
In Figure 1, IO is changed at positive edges of SCLK. The
MICRF610 samples the IO line at negative edges. The
value of the R/W bits is always “0” for writing.
Writing to All Registers
After a power-on, all writable registers must be written.
This is described here.
Writing to all register can be done at any time. To get the
simplest firmware, always write to all registers. The price
to pay for the simplicity is increased write-time, which
leads to increased time for changing the way the
MICRF610 works.
What to write
Field
Comments
Address:
‘000000’ (address of the first register to write to, which is 0)
R/W bit:
“0” for writing
Values:
1
st Octet: wanted values for ControlRegister0. 2nd Octet: wanted
values for ControlRegister1 and so on for all of the octets. So the
22
nd octet: wanted values for ControlRegister21. Refer to the
specific sections of this document for actual values.
Table 4. “Address” and “R/W bit” together make 1 octet.
In total, 23 octets are clocked into the MICRF610.
