Use CS, SCLK, and IO to get access to the
control registers in MICRF505.
SCLK is user-controlled.
Write to the MICRF505 at positive edges
(MICRF505 reads at negative edges).
Read from the MICRF505 at negative edges
(MICRF505 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 (“load_en” = 1).
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.
