... PixArt Imaging Inc. PAN3401 7. Mouse Mode Selection The Set Sampling Rate command is used to set the device operating modes. Whenever the mouse received command 'FF', it will reset to standard mode (2D3B) mode. After power-on reset is initiated, the mouse is set to standard PS/2 mode. The Device ID is available through the PS/2 Read Device Type (0xF2) command. For a device in standard 2D mode, the device will report 0x00 ...

... CLK to inhibit the PAN3401 output after the PAN3401 has started a transmission. If this occurs prior to the rising edge of the tenth clock (parity bit), the PAN3401 internally stores the data package in its buffer and return DATA and CLK to an active level. If the contention does not occur by the tenth clock, the transmission is complete ...
