Port reset state
The reset state of the I/O ports is GPIO input floating. Exceptions are P1[19:16] and P0.13
which are configured as JTAG alternate functions:
●
The JTAG inputs (JTDI, JTMS and JTDI) are configured as input floating and are ready
to accept JTAG sequences.
●
The JTAG output JTDO is configured as floating when idle (no JTAG operation) and is
configured in output push-pull only when serial JTAG data must be output.
●
The JTAG output RTCK is always configured as output push-pull. It outputs '0' level
during the reset phase and then outputs the JTCK input signal resynchronized 3 times
by the internal AHB clock.
●
The GPIO_PCx registers do not control JTAG AF selection, so the reset values of
GPIO_PCx for P1[19:16] and P0. 13 are the same as other ports. Refer to the GPIO
section of the STR750 Reference Manual for the register description and reset values.
●
P0.11 and P0.00 are sampled by the boot logic after reset, prior to fetching the first
word of user code at address 0000 0000h.
●
When booting from SMI (and only in this case), the reset state of the following GPIOs is
"SMI alternate function output enabled":
–
P0.07 (SMI_DOUT)
–
P0.05 (SMI_CLK)
–
P0.04 (SMI_CS0)
–
P0.06 (SMI_DIN)
Note that the other SMI pins: SMI_CS1,2,3 (P0.12, P0.11, P0.10) are not affected.
To avoid excess power consumption, unused I/O ports must be tied to ground.
