HT1632CFunctional DescriptionDisplay Memory RAMThe static display memory (RAM) is organized into 644bits or 964 bits and is used to store the display data. If32 ROW & 8 COM is selected, the RAM size is 644bits. If 24 ROW & 16 COM is selected, the RAM size is964 bits. The contents of the RAM are directly mappedto the contents of the LED driver. If the data in RAM isset to 1, the corresponding LED will be lighted. Data inthe RAM can be accessed by the READ, WRITE, andREAD-MODIFY-WRITE commands. The contents ofthe RAM can be read or written from bit 0 of the specificaddress. The following is a mapping from the RAM tothe LED pattern:COM7 COM6 COM5 COM4 COM3 COM2 COM1 COM0ROW0 01H 00HROW1 03H 02HROW2 05H 04HROW3 07H 06HROW4 09H 08HROW5 0BH 0AHROW6 0DH 0CHROW7 0FH 0EHROW8 11H 10HROW9 13H 12HROW10 15H 14HROW11 17H 16HROW12 19H 18HROW13 1BH 1AHROW14 1DH 1CHROW15 1FH 1EHROW16 21H 20HROW17 23H 22HROW18 25H 24HROW19 27H 26HROW20 29H 28HROW21 2BH 2AHROW22 2DH 2CHROW23 2FH 2EHROW24 31H 30HROW25 33H 32HROW26 35H 34HROW27 37H 36HROW28 39H 38HROW29 3BH 3AHROW30 3DH 3CHROW31 3FH 3EHD3 D2 D1 D0Addr.DataD3 D2 D1 D0Addr.Data32 ROW & 8 COM for 644 Display RAMRev. 1.20 5 June 28, 2011
