42 / 96 page ![]() ST7632 Ver 1.7 42/96 2006/08/15 (9) Page address set (PASET) Command: 1; Parameter: 2 (75H) When MPU makes access to the display data RAM, this command and succeeding parameters are used to specify the page address area. As the addresses are incremented from the start to the end page in the page-direction scan, the column address is incremented by 1 and the page address is returned to the start page. Note that the start and end page must be specified as a pair. Also, the relation “start page <end page” must be maintained.

As the addresses are incremented from the start to the end column in the column-direction scan, the page address is incremented by 1 and the column address is returned to the start column. Note that the start and end page must be specified as a pair. Also, the relation “start column <end column” must be maintained.

P10: Normal/Reverse display of the page address. P10=0: Normal and P10=1: Reverse P11: Normal/Reverse turn of column address. P11=0: Normal rotation and P11=1: Reverse rotation. P12: Address-scan direction. P12=0: In the column direction and P12=1: In the page direction. |
