the PMEMCR register. When data is read out up to the border of the set page, the
controller completes the page reading operation. The start data of the next page is read
in the normal cycle. The following data is set to page read again.
The TMP92CH21 supports ROM access of the page mode. ROM access of the page
ROM page mode is set by the page ROM control register (PMEMCR). Setting
The number of read cycles is set by the <OPWR1:0> of the PMEMCR register.
The page size (the number of bytes) of ROM in the CPU size is set by the <PR1:0> of
