3.3.5
This command is used to send a new device configuration to
the CY8C95xx. It is followed by 146 data bytes according to
Table
bytes (00h-91h). If the CRC check fails or an incomplete block
is sent, then the slave will respond with a NAK and the device
will not use the data. This gives the user ‘flat-address-space’
access to all device settings.
To set the current device configuration the user must:
If the CRC check passes, then the device will use the new set-
tings immediately.
Content of the data block is described in
3.3.6
This command is used to read the current device configuration.
It gives the user ‘flat-address-space’ access to all device set-
tings.
To read device configuration the user must:
3.3.7
This command is used to immediately reconfigure the device
with actual POR defaults from EEPROM. It has the same effect
on the registers as a POR.
Write command 05h;
Write 146 data bytes with new values of registers;
Write 1 CRC byte calculated as XOR of previous 146 data
bytes.
Write command 06h;
Read 146 data bytes (see
Read 1 CRC byte.
