(see the control data description for details.) if a key on one of the lines corresponding to a ks1 to ks6 pin wh ich is set high is pressed, t he oscillator on the osc pin is started and a key scan is performed. keys are scanned until all ke ys 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) t he BU97550KV-M outputs a key data read request (a low level on sdo) to the controller. the controller acknowledges this reques t and reads the key data. however, if sce is high during a seria l data transfer, sdo will be set high. after the controller reads the key data, the key data read req uest is cleared (sdo is set high) and the BU97550KV-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) (note 29) these diodes are required to reliable recognize multiple key pre sses 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 l ines are pressed at the same time. figure 23. key scan operation in sleep mode multiple key presses although the BU97550KV-M is capable of key scanning without inse rting 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 presse s of three or more keys should check the key data for three or more 1 bit and ignore such data. 9840t[s] 9840t[s] serial data transfe r serial data transfe r key address(43h) serial data transfe r key address key data read key data read key data read request key data read request key input 2 (ks6 line) key scan ce di d0 t= 1 fosc 43h) (l)ks1 (l)ks2 (l)ks3 (l)ks4 (l)ks5 (l)ks6 kl1 kl2 kl3 kl4 kl5 when any one of these keys is pressed, the oscillator on the osc pin is started and the keys are scanned.
