DESCRIPTION
-
Port5 input data register
The DATAIN5 indicates the status of each GPIO17~GPIO5 pin
regardless of its operation mode. The reserved bits will be read
as 0s.

-
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
