STB

W/R

Write and read for different functions, as flag bit or mask bit, for

the HFPWR assertion interrupt. Write 1 allow interrupt, write 0

mask interrupt; Read 1 when interrupt asserted, 0 if no interrupt.

Also see DATAB[ ], POSB[ ] and NEGB[ ] for the status and

conditions.

STA

W/R

Write and read for different functions, as flag bit or mask bit, for

the "enable key" push-button assertion interrupt. Write 1 allow

interrupt, write 0 mask interrupt; Read 1 when interrupt asserted,

0 if no interrupt. Also see DATAA[ ], POSA[ ] for the status and

conditions.
