Configuration
The PDC clock is generated by the Power Manager. The PDC also depends on the HSB-HSB
bridge clock. Before using the PDC, the programmer must ensure that the PDC clock and HSB-
HSB bridge clock are enabled in the Power Manager.
To prevent bus errors the PDC operation must be terminated before entering sleep mode
The PDC has an interrupt line for each channel connected to the Interrupt Controller via the cor-
responding peripheral. Handling the PDC interrupt requires programming the interrupt controller
before configuring the PDC.
Before using each PDC channel the corresponding peripheral has to be configured correctly.
The PDC channels user interface enables the user to configure and control the data transfers for
each channel. The user interface of a PDC channel is integrated into the user interface of the
peripheral (offset 0x100), which it is related to.
Per peripheral, it contains four 32-bit Pointer Registers (RPR, RNPR, TPR, and TNPR) and four
16-bit Counter Registers (RCR, RNCR, TCR, and TNCR).
The size of the buffer (number of transfers) is configured in an internal 16-bit transfer counter
register, and it is possible, at any moment, to read the number of transfers left for each channel.
The memory base address is configured in a 32-bit memory pointer by defining the location of
the first address to access in the memory. It is possible, at any moment, to read the location in
memory of the next transfer and the number of remaining transfers. The PDC has dedicated sta-
tus registers which indicate if the transfer is enabled or disabled for each channel. The status for
each channel is located in the peripheral status register. Transfers can be enabled and/or dis-
abled by setting TXTEN/TXTDIS and RXTEN/RXTDIS in PDC Transfer Control Register. These
control bits enable reading the pointer and counter registers safely without any risk of their
changing between both reads.
The PDC sends status flags to the peripheral visible in its status-register (ENDRX, ENDTX,
RXBUFF, and TXBUFE).
ENDRX flag is set when the PERIPH_RCR register reaches zero.
RXBUFF flag is set when both PERIPH_RCR and PERIPH_RNCR reach zero.
ENDTX flag is set when the PERIPH_TCR register reaches zero.
TXBUFE flag is set when both PERIPH_TCR and PERIPH_TNCR reach zero.
These status flags are described in the peripheral status register.
