SMT332/372 User Manual
Flash
A 256k byte Flash ROM device is fitted to the ‘C6x01 EMI. This device is byte
accessed using strobe CE1 (from 0x0140 0000 to 0x0143 ffff)
This device contains boot code for the ‘C6x01 and configuration data for the FPGA.
A software protection algorithm is in place to protect erroneous altering of the
device’s contents. Please contact Sundance for further information with regard to re-
programming this device.
Comm ports
The ‘C6x01 does not include, within the device itself, any means of communicating
high speed data to other processors. For operation in a TIM 40 environment, 4
communication (comm) ports are provided.
The comm ports on the SMT332/372 will interface to any standard ‘C4x comm port.
The comm ports can operate in two modes. The first mode is for the ‘C6x01 to
transfer data to the port directly using a polling technique. The second mode is for
the ‘C6x01’s DMA controller to be set to event triggered and select the appropriate
trigger (INT4..7) for the transfer.
The minimum comport data rate is about 9.2MB/s.
The following table shows the ‘C6x01 address map for the comm port interface.
