What is Flash page size in controller MC9S12XDP512?

I am writing Flash Driver for MC9S12XDP512.

I have query regarding Flash page size for MC9S12XDP512.

Query: What is Flash page size in controller MC9S12XDP512?

My Flash driver only provides page/pages write operation.

In MC9S12XDP512 controller datasheet only sectors are defined for 512K flash module.

No page is defined. Sector size is 1KBytes.

Sector size has to be an integer multiple of the page size.

In Burst programming 64 words in a row can be programmed consecutively using command pipeline operation.

So is this Burst programming mode related to Flash Page size?

Thanks In Advance!!!

Dear Sanjivani,

I think ur having the answer with you , since flash size is 512K and you know that sector size is 1k.

now find how many pages are there in flash?

it has 32 pages (0xE0---0xFF) so u wil get size of flash page which is 16K.
