Other Parts Discussed in Thread: TMS570LS20216
I've connected to a TMS570 device with CCSv4; and am trying to write to the NHET register HETGCR (0xFFF7 B800).
Used the TMS570LS20216 GEL file. Have not loaded any code.
Opening a memory window to address 0xFFF7 B800, I try to write a 0x1 to this address to turn on the NHET.
However, CCS reads back the default value 0 - the write doesn't take effect.
I found in Chapter 5 of the TMS570 TRM (SPNU489) that there are peripheral power down (0xFFFFE0Ax) and peripheral
memory power down registers and (0xFFFFE07x) that need to be written, since the default is for peripherals to be in power down.
However, I wrote to these registers to remove the peripherals from power down (all peripheral selects and peripheral memory selects)
but still cannot access the NHET memory.
Not finding anything else in the manual to indicate that they should still be powered down. Any suggestions?
