Table 17. McBSP Registers for C620x/C670x DSP
Acronym Register Name
RBR † Receive buffer register
RSR † Receive shift register
XSR † Transmit shift register
‡
DRR Data receive register
DXR Data transmit register
SPCR Serial port control register
RCR Receive control register
XCR Transmit control register
SRGR Sample rate generator register
MCR Multichannel control register
RCER Receive channel enable register
XCER Transmit channel enable register
PCR Pin control register
†
The RBR, RSR, and XSR are not directly accessible via the CPU or the DMA/EDMA controller.
‡
The CPU and DMA/EDMA controller can only read this register; they cannot write to it.
§
Available only on C6202(B) DSP and C6203(B) DSP.
84 Multichannel Buffered Serial Port (McBSP)
Table 17 lists the McBSP registers and their memory addresses for the
C620x/C670x DSP,
C621x/C671x DSP, and Table 19 lists the McBSP registers for the C64x DSP.
See the device-specific datasheet for the memory address of these registers.
The McBSP control registers are accessible only via the peripheral bus (see
Figure 1). You should halt the McBSP before making changes to the serial port
control register (SPCR), receive control register (RCR), transmit control
register (XCR), and pin control register (PCR). Changes made to these
registers without halting the McBSP could result in an undefined state.
