Debounce Clock Selection
These 3 bits are used to select the clock rate for de-bouncer circuit. The
relationship between the system clock HCLK and the de-bounce clock
TCLK_BUN is as follows: TCLK_BUN = HCLK / 2^DBCLKSEL
Debounce circuit enable for GPIO19 (nIRQ3)
1 = enable
0 = disable
Debounce circuit enable for GPIO18 (nIRQ2)
1 = enable
0 = disable
Debounce circuit enable for GPIO17 (nIRQ1)
1 = enable
0 = disable
Debounce circuit enable for GPIO16 (nIRQ0)
1 = enable
0 = disable
