+ 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.
