ADS Functional Description
5.7 I
There are two I
features:
a. Slave Mode is available but not used on the board
5.7.1 Serial EEPROM for MPC8560 Boot
a. Boot setting
b. Slave Mode allows to verify MSC8144 multi device configuration mode
The serial EEPROM is an I
(EEPROM) organized as 32 K × 8. Serial interface supports 400KHz protocol. Hardware write
pin is controlled by the BOOTWP bit BCSR0[4]. Its default value is high, which protects the
device against undesirable write operation. Chip Enable pins E0, E1, and E2 are grounded to
provide MPC8560 boot function.
