Master mask for the interrupt
Description
Notes
0: Enable the interrupt output at the INTB pin. The timing of switching
action is determined by Wait bit.
1: Disable the interrupt output at the INTB pin. Under this condition, INTB
outputs low voltage, and the signal switches for attached accessories
except JIG cable will not be turned on. The baseband shouldn’t read
interrupt registers before this bit is changed to 0.
1
R/W
Wait
1
Wait or not to wait for the command from the baseband before turning on
the analog or digital switches for attached accessory
0: Wait until this bit is changed to 1. Turn on the switches immediately
when this bit is changed to 1.
1: Wait for only the time programmed by the Switching Wait bits in Timing
Set 2 register before turning on the switches.
2
R/W
Manual S/W
1
Manual or automatic switching of the switches
0: manual: the switches are controlled by the Manual S/W registers.
1: auto: the switches are controlled by the Device Type registers

Interrupt behavior selection
0: Enable the ADC conversion periodically and report the ADC Result
changes on ID pin to the host.
1: Enable the key press monitor circuit to detect the ID pin status changes
and report the key press events to the host.

R/W
Switch_Open
1
Switch connection selection
0: Open all switches
1: Switch selection according to the Manual S/W bit.
