HL15604
Key input 1
3) In sleep mode
The pins KS1 to KS6 are set to high or low by the S0 and S1 bits in the
sleep mode control register.
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 pre-
sses are recognized by determining whether multiple key data bits are set.
If a key is pressed for longer than 800T ( where T=1/fosc ) the HL14104
outputs a key data read request (a low level on SO) to the controller. The
controller acknowledges this request and reads the key data. However, if
CE is high during a serial data transfer, SO will be set high.
After the controller reads the key data, the key data read request is cleared
( SO is set high ) and the HL14104 performs another key scan. However
this does not clear sleep mode. Also note that SO, being an open-drain
output, requires a pull-up resistor ( between 1 and 10 K).
Sleep mode key scan example
Example : S0 = 0, S1 = 1 ( sleep with only KS6 high )
