Address
Note: The touch screen controller block decodes APB address bits PADR[6:2] only. If the decode

for the PSEL_HATSH APB block select is a larger block size in the APB decoder, the
registers will be repeated through memory. Touch screen controller registers are intended
to be word accessed only. Since the least significant bytes of the address bus are not
decoded, byte and half word accesses are not allowed and may have unpredictable
results.
