Description
This bit is used to disable the
Energy_Det_Debounce_Low Logic from
debouncing the GPHY Energy_Det_APD signal
going low. When disabled, the Energy_Det signal
will go low if the GPHY Energy_Det input signal
is low for at least 640 ns.
0: Enable De-bounce Low
1: Disable De-bounce Low
This bit is used to disable the
Energy_Det_Debounce_High Logic from
debouncing the GPHY Energy_Det_APD signal
going high. When disabled, the Energy_Det
signal will go high if the GPHY Energy_Det input
signal is high for at least 640 ns.
0: Enable De-bounce High
1: Disable De-bounce High
This parameter is used to control the debounce
limit of the GPHY Energy_Det_APD signal going
high.
00: 128 million CPMU clocks (5 seconds if CPMU
clock frequency is 25 MHz)
01: 256 million CPMU clocks (10 seconds if
CPMU clock frequency is 25 MHz)
10: 512 million CPMU clocks (20 seconds if
CPMU clock frequency is 25 MHz)
11: 1024 million CPMU clocks (40 seconds if
CPMU clock frequency is 25 MHz)
