Internal RAM parity error address register (RAMPADD)
The RAMPAD register is a 16-bit register that latches the internal RAM address causing the first
parity error after hardware reset was released or RAMERR register was cleared.
This register can be read or written in 16-bit units.
Reset input clears this register to 8000H.
Caution:
Do not read the RAMPADD register, when all internal RAM parity error flags RAEn
(n = 0 to 3) are cleared. If a parity error is detected and the RAMPADD register is read
before the respective RAEn flag is set, the read value might be invalid.
