All rights reserved. www.rohm.com TSZ22111・15・001 14.Jul.2016 Rev.004 【 0x11-0x12 : Sensor State】 Name: STATE_SIN Address: 0x11-0x12 Description: This register indicates the status of switch-on or switch-off for each sensor. 1 : Switch-on.(Register “SIN” > Register “ON”) 0 : switch-off. (Register “SIN” < Register “OFF”) Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x11 SIN7 SIN6 SIN5 SIN4 SIN3 SIN2 SIN1 SIN0 0x12 SIN15 SIN14 SIN13 SIN12 SIN11 SIN10 SIN9 SIN8 R/W R R R R R R R R Initial val. 0 0 0 0 0 0 0 0 【 0x13-0x15 : Detection Switch-On】 Name: DETECT_ON Address: 0x13-0x15 Description: This register indicates the change from Off to On every switch. Since SW 0-15 supports multiple pressed, each switch has a bit recognition. And the matrix key does not correspond to multiple press, so matrix switch is indicated by 1 bit for ON detection (MAT) and 6 bits for 36 positions (KEY). Logical OR of each SW and MAT will be ONDET interrupt source register. 1 : Detect On. 0 :Cleared.

Since SW 0-15 supports multiple pressed, each switch has a bit recognition. And the matrix key does not correspond to multiple press, so matrix switch is indicated by 1 bit for OFF detection (MAT) and 6 bits for 36 positions (KEY). Logical OR of each SW and MAT will be OFFDET interrupt source register. 1 : Detect Off. 0 :Cleared.

Since SW 0-15 supports multiple pressed, each switch has a bit recognition. And the matrix key does not correspond to multiple press, so matrix switch is indicated by 1 bit for CONT detection (MAT) and 6 bits for 36 positions (KEY). Logical OR of each SW and MAT will be CONTDET interrupt source register. 1 : Detect continued touch. 0 :Cleared.
