Writing
MICRF507
This method is used to write either to one register (see
?
Clock in one or more bytes, MSB of each byte
Figure 1), or any number of registers with consecutive
addresses up to all 22 writeable registers (see Figure 2) in
a single transaction.
Procedure:
? Bring CS active (high). IO is initially an input (and
remains so for the duration of the transaction).
first.
? Bring CS low to end the transaction.
Bits passing through IO are clocked serially into pre-
buffers, then transferred in parallel to the actual registers
upon de-assertion of CS.
?
Clock in a byte consisting of the address bits and
the R/W bit. The first seven bits are the address
(starting with MSB) of the register, or the first
register if more than one, to be written. The eighth
bit is the R/W bit, which is 0 as this is a write
operation.
