Register Name: Movctrl (7 bits)
Access Type: Read/Write
Function: In stream mode, during navigation calculation, the AT77C104B must
interrupt the host when a maximum absolute X or Y movement is detected (second and third
navigation registers). The MOVECTRL register enables you to control this value. This value can
be set as the minimum finger movement value at which the pointing device makes a
displacement.
For example, when MOVCTRL = 0b0001001, an interruption to the host is generated when the
absolute X movement register (second navigation register) or absolute Y movement register
(third navigation register) is greater than 0b00010010.
Note:
• MOVCTRL: Generates an interrupt when the second or third navigation register (X or Y
absolute movement) is greater than the value programmed in the Movectrl register.

The Movctrl register should not be changed once the navigation mode is selected.
