/*
|
||
|
|
There are 2 sets of general I/O -->
|
||
|
|
1. GPIO (shared between ARM & DSP, configured by ARM)
|
||
|
|
2. MPUIO which can be used only by the ARM.
|
||
|
|
|
||
|
|
Base address FFFB:5000 is where the ARM accesses the MPUIO control registers
|
||
|
|
(see 7.2.2 of the TRM for MPUIO reg definitions).
|
||
|
|
|
||
|
|
Base address E101:5000 is reserved for ARM access of the same MPUIO control
|
||
|
|
regs, but via the DSP I/O map. This address is unavailable on 1510.
|
||
|
|
|
||
|
|
Base address FFFC:E000 is where the ARM accesses the GPIO config registers
|
||
|
|
directly via its own peripheral bus.
|
||
|
|
|
||
|
|
Base address E101:E000 is where the ARM can access the same GPIO config
|
||
|
|
registers, but the access takes place through the ARM port interface (called
|
||
|
|
API or MPUI) via the DSP's peripheral bus (DSP I/O space).
|
||
|
|
|
||
|
|
Therefore, the ARM should setup the GPIO regs thru the FFFC:E000 addresses
|
||
|
|
instead of the E101:E000 addresses. The DSP has only read access of the pin
|
||
|
|
control register, so this may explain the inability to write to E101:E018.
|
||
|
|
Try accessing pin control reg at FFFC:E018.
