Power on Reset
When applying voltage to the MICRF610 a power on reset
state is entered. During the time period of power on reset,
the MICRF610 should be considered to be in an unknown
state and the user should wait until completed (See Table
6). The power on reset timing given in table 6 is covering
all conditions and should be treated as a maximum delay
time. In some application it might be beneficial to minimize
the power on reset time. In these cases we recommend to
follow below procedure:

Programming Summary

•

•
Use CS, SCLK, and IO to get access to the control
registers in MICRF610.
SCLK is user-controlled.
Write to the MICRF610 at positive edges
(MICRF610 reads at negative edges).
Read from the MICRF610 at negative edges
(MICRF610 writes at positive edges)
After power-on: Write to the complete set of
control registers.
Address field is 7 bits long. Enter msb first.
R/W bit is 1 bit long (“1” for read, “0” for write)
Address and R/W bit together make 1 octet
All control registers are 8 bits long. Enter/read msb
in every octet first.
Always write 8 bits to/read 8 bits from a control
register. This is the case for registers with less
than 8 used programming bits as well.
Writing: Bring CS high, write address and R/W bit
followed by the new values to fill into the
addressed control register(s) and bring CS low for
loading, i.e., activation of the new control register
values.
Reading: Bring CS high, write address and R/W
bit, set IO as an input, read present contents of the
addressed control register(s), bring CS low and
set IO an output.
