31.8.3 Performing a Page Write

To execute Page Write, set up the address in the Z-pointer, write “0x0000101” to SPMCSR, and execute SPM within four clock cycles after writing SPMCSR. The data in R1 and R0 is ignored. The page address must be written to PCPAGE ([Z5:Z1]). Other bits in the Z-pointer must be written to zero during this operation.

• Page Write to the RWW section: The NRWW section can be read during the Page Write
• Page Write to the NRWW section: The CPU is halted during the operation
