Read-out of 24 bit data
set up and R/W bit is set to “H”, when reading data of TC9446F from a MCU during program
operation is set up.

to data buffer. The procedure of read-out of 24 bit data is shown in Figure 4.
(waiting for becoming to MIACK = “L” at the MIACK = “H”)
(waiting for becoming to MIACK = “L” at the MIACK = “H”)
The number of words of data read while data required for the 16 bit address in a 24 bit command is
And, after transmitting a 24 bit command, MIACK = “L” is checked and 24 bit data of the required
MIACK = “L” is checked after command transmission for waiting to set data which should be read

A 16 bit address and a transmission word
number are set up.
It is possible to read out the 24 bit data
until 16 word maximum.
