To provide data exchange between blocks, the following buses are implemented:
All internal buses on the DSP56300 family members are 24-bit buses. See
2.4.5
The DMA block has the following features:
Freescale Semiconductor
PC—program counter register
SR—Status register
LA—loop address register
LC—loop counter register
VBA—vector base address register
SZ—stack size register
SP—stack pointer
OMR—operating mode register
SC—stack counter register
Peripheral input/output expansion bus (PIO_EB) to peripherals
Program memory expansion bus (PM_EB) to program memory
X memory expansion bus (XM_EB) to X memory
Y memory expansion bus (YM_EB) to Y memory
Global data bus (GDB) between registers in the DMA, AGU, OnCE, PLL, BIU and PCU, as well
as the memory-mapped registers in the peripherals
DMA data bus (DDB) for carrying DMA data between memories and/or peripherals
DMA address bus (DAB) for carrying DMA addresses to memories and peripherals
