I) Initial Setting
[1] Command for Self-operation mode
By executing
‘
Command for Self-operation mode
’
, it is possible to transfer the mode from
“
Training mode
”
to
“
Self-operation mode
”
.
[2] Command for Training mode
By executing
‘
Command for Training mode
’
, it is possible to transfer the mode from
“
Self-operation mode
”
to
“
Training mode
”
. Also any command except
‘
Command for Training mode
’
is not available while AK2570
operates in
“
Self-operation mode
”
.
[3] Command for Selecting AD1
‘
Command for selecting AD1
’
is available in
“
Training mode
”
. This command sets that AD1 (the A to D
converter for the input voltage to VPDIN-pin) is enable for the operation and the selector between AD1 and
RVPD register is available. After this command is performed, the 8bits digital data of the VPDIN-pin signal
encoded in AD1 is stored in RVPD register by executing
‘
Activating internal circuit - Command for A/D
operation
’
.
[4] Command for Selecting AD2
‘
Command for selecting AD2
’
is available in
“
Training mode
”
. This command sets that AD2 (the A to D
converter for the output voltage from T-SENSE) is enable for the operation and the selector between AD2 and
RTMP register is available. After this command is performed, the 8bits digital data of the T-SENSE output
encoded in AD2 is stored in RTMP register by executing
‘
Activating internal circuit - Command for A/D
operation
’
.
II) Activating internal circuit
[1] Command for A/D operation
‘
Command for A/D operation
’
makes that the selected A to D converter (AD1 or AD2) operates and the
selected register (RVPD register or RTMP register) stores the data generated in the A to D converter selected by
executing
‘
Command for Selecting AD1
’
or
‘
Command for Selecting AD2
’
. Also this command makes only
that the selected register stores the 8bits digital data generated by the selected A to D converter.
[2] Command for Resetting data in RDA1-3
‘
Command for Resetting data in RDA1-3
’
sets that RDA1 ~ RDA3 registers hold the data retained in
EEPROM which address is nominated by the data in RTMP register. Also this command is always available in
“
Training mode
”
and independent with the selector set by
‘
Command for Selecting AD1
’
or
‘
Command for
Selecting AD2
’
.
III) Register Access
[1] Command for reading the data in the register (READ-REG
）
It is able to read the data held in the nominated register by executing
‘
READ-REG
’
command.
[2] Command for Writing the data in the register (WRITE-REG)
It is able to write the data in the nominated register by executing
‘
WRITE-REG
’
command.
