Errata Description
Description (added 1/27/98):
Applies
to Mask
2J26D
When activity passes from one DMA channel to another and the DMA
interface accesses external memory (which requires one or more wait
states), the DACT and DCH status bits in the DMA Status Register
(DSTR) may indicate improper activity status for DMA Channel 0
(DACT = 1 and DCH[2:0] = 000).
Workaround:
None.
Description (added 7/21/98):
2J26D
The DRAM Control Register (DCR) should not be changed while refresh
is enabled. If refresh is enabled only a write operation that disables refresh
is allowed.
Workaround:
First disable refresh by clearing the BREN bit, than change other bits in the
DCR register, and finally enable refresh by setting the BREN bit.
