3.6.1.2 Device Type
Selection for
Optional Boot
PROM (Socket J28)
The optional Boot PROM socket supports the use of
- Programmable 5V Flash devices
- EPROM (OTP)
- EEPROM
This is controlled by switch SW5-2.
3.6.1.3 Programming
the Boot
PROM Devices
The programming of Boot PROM devices is supported for the default
Boot PROM (socket J36) for 12V Flash devices and for the optional Boot
PROM socket J28 for 5V Flash or EEPROM devices.
For correct programming, a communication sequence to the Boot PROM
devices must be used which is defined by the manufacturer of the device.
SEE ALSO: For further details, please refer to the data sheets in
Section 4, ‘Circuit Schematics and Data Sheets,’ on page 115.
The programming to the Boot PROM devices is dependent on switch
SW5-3.
The status of switch SW5-3 is connected to the PI/T #2.
CAUTION: PI/T #2 pin PC2 must be programmed as an input.
