Figure 3-145. FlexRay CC to HCS12 Device Connection with HCS12 EBI Paged Mode Support
HCS12
The HCS12 interface module accepts only aligned 16-bit wide read/write and 8-bit wide read
transactions. The FlexRay CC module does not support 8-bit wide write accesses. The error
indication bit ILLADR (illegal address) is raised in the CHIER (see
Register
transaction is performed (detected if ADR[0] is equal to 1 or if LSTRB is equal to 1). Data 0x0000
is presented to the host in this case.
the RW_CC# signal indicates the direction of data transfer for a transaction.
INT_CC# is an interrupt line that can be used for requesting, by means of the internal interrupt
controller, a service routine from the HCS12 device.
