LS1028A GPIOs Reg

mkraj — Mon, 30 Dec 2024 10:50:07 GMT

1. In LS0128A Reference Manual, Section "The GPIO module as implemented on the chip" was mentioned. Where is this section available?

2. I can see 3 sets of GPIOs GPIO 1 to 3. How are these different? It seems we can not use GPIO1_DAT0 and GPIO2_DAT0 simultaneously. Is this correct?

Thank you

1. This is a mistake in LS1028ARM, there is no this section "The GPIO module as implemented on the chip".

2. The base addresses of these 3 sets are different.

GPIO1 base address: 230_0000h
GPIO2 base address: 231_0000h
GPIO3 base address: 232_0000h

You can use GPIO1_DAT0 and GPIO2_DAT0 simultaneously.
