General-Purpose I/O Pins

McBSP Pins as General-Purpose I/O
3.9.2
HPI Data Pins as General-Purpose I/O
TMS320VC5410A
Fixed-Point Digital Signal Processor
SPRS139G–NOVEMBER 2000–REVISED JANUARY 2005
In addition to the standard BIO and XF pins, the 5410A has pins that can be configured for
general-purpose I/O. These pins are:
18 McBSP pins — BCLKX0/1/2, BCLKR0/1/2, BDR0/1/2, BFSX0/1/2, BFSR0/1/2, BDX0/1/2
8 HPI data pins — HD0-HD7
The general-purpose I/O function of these pins is only available when the primary pin function is not
required.
When the receive or transmit portion of a McBSP is in reset, its pins can be configured as
general-purpose inputs or outputs. For more details on this feature, see Section Section 3.4.
The 8-bit bidirectional data bus of the HPI can be used as general-purpose input/output (GPIO) pins when
the HPI is disabled (HPIENA = 0) or when the HPI is used in HPI16 mode (HPI16 = 1). Two
memory-mapped registers are used to control the GPIO function of the HPI data pins—the gen-
eral-purpose I/O control register (GPIOCR) and the general-purpose I/O status register (GPIOSR). The
GPIOCR is shown in Figure 3-23.

The direction bits (DIRx) are used to configure HD0-HD7 as inputs or outputs.
The status of the GPIO pins can be monitored using the bits of the GPIOSR. The GPIOSR is shown in
Figure 3-24.
