(see the control data description for details.) if a key on one of the lines corresponding to a ks1 to ks6 pin which is set high is pressed, the oscillator on the osc pin is started and a key scan is performed. keys are scanned until all keys are released. multiple key presses are recognized by determining whether multiple key data bits are set. if a key is pressed for longer than 9840t(s)(where t=1/fosc) the BU97530KVT-M outputs a key data read request (a low level on sdo) to the controller. the controller acknowledges this request and reads the key data. however, if sce is high during a serial data transfer, sdo will be set high. after the controller reads the key data, the key data read request is cleared (sdo is set high) and the BU97530KVT-M performs another key scan. however, this does not clear sleep mode. also note that sdo, being an open-drain output, requires a pull-up resistor (between 1 and 10k ? ). sleep mode key scan example example: bu0=0, bu1=0, bu2=1 (sleep with only ks6 high) (note22) these diodes are required to reliable recognize multiple key presses on the ks6 line when sleep mode state with only ks6 high, as in the above example. that is, these diodes prevent incorrect operations due to sneak currents in the ks6 key scan output signal when keys on the ks1 to ks5 lines are pressed at the same time. figure 19. key scan operation in sleep mode multiple key presses although the BU97530KVT-M is capable of key scanning without inserting diodes for dual key presses, triple key presses on the ki1 to ki5 input pin lines, or multiple key presses on the ks1 to ks6 output pin lines, multiple presses other than these cases may result in keys that were not pressed recognized as having been pressed. therefore, a diode must be inserted in series with each key. applications that do not recognize multiple key presses of three or more keys should check the key data for three or more 1 bit and ignore such data.
