CALRAM Operation
22.4.6.3
If overlay is enabled and CRAMOVLCR[DERR] is set, then any normal L-bus array access that falls
within any of the eight enabled overlay regions generates a machine-check exception; otherwise the access
terminates normally without asserting data error. The L-bus write accesses cause the data to be written
regardless of whether the DERR bit is set or not.
For example, if overlay region 1 is programmed such that it is enabled and its region size is 256 bytes, then
any L-bus access to address in the range of 0x3F F200 – 0x3F F2FF generates machine check exception
if the DERR bit is set in CRAMOVLCR register. The other portion of region 1 from 0x3F F300 to 0x3F
F3FF can be used as normal (non-overlay) array.
22.4.6.4
Write accesses to the overlaid U-bus Flash regions are ignored completely by the CALRAM module.
22.5
The following section describes the CALRAM programmer’s model. The CALRAM has one register
(CRAMMCR) for configuring the CALRAM array and one register dedicated to factory test. In addition,
there are eight 32-bit region base address registers for calibration purposes and a 32-bit overlay
configuration register. The region base address registers hold the base address for the Flash region and
region size that need to be overlaid by the CALRAM. The overlay configuration register provides three
bits (OVL, DERR, and CLSP) that are needed for overlay configuration. The CALRAM ownership trace
register (CRAM_OTR) is provided to support a separate module called a READI module. Access to all
CALRAM registers requires the bus master to be in supervisor data mode. On a privilege violation, the
register is not accessed and the access generates an error.
