ST7565R start line on display is the 31st

Hello,
I'm using the library ST7565.h and all is fine, except the buffer is drawn over the display starting from line 32 down to bottom, then image continues from line 0 till line 31. Actually the screen image is split on horizontal half screen.
I read inside the documentation indeed this is a feature, in order to obtain scrolling/paging effects, but I would to set as line 0 the first one to be written (as in normal case is).
Then: what is the command/function that allows this using the library ST7565.h?
Thank you for yr reply

Hi,
I've solved by changing:
const uint8_t pagemap = { 3, 2, 1, 0, 7, 6, 5, 4 };

into:
const uint8_t pagemap = { 7, 6, 5, 4, 3, 2, 1 ,0 };

Thanks anyway, hoping this can help other users.
