On the 280x, the GPIO MUX can multiplex up to three independent peripheral signals on a single GPIO
pin in addition to providing individual pin bit-banging IO capability. The GPIO MUX block diagram per pin
is shown in
Figure 4-16
. Because of the open drain capabilities of the I
2
C pins, the GPIO MUX block
diagram for these pins differ. See the
TMS320x280x System Control and Interrupts Reference Guide
(literature number SPRU712) for details.
A.
x stands for the port, either A or B. For example, GPxDIR refers to either the GPADIR and GPBDIR register
depending on the particular GPIO pin selected.
GPxDAT latch/read are accessed at the same memory location.
