• 16-bit modulus down counter with interrupt
Features
2.4.8 Flash memory
The PXD10 microcontroller has the following flash memory features:
• Up to 1 MB of burst flash memory
— Typical flash memory access time: 0 wait-state for buffer hits, 2 wait-states for page buffer miss
at 64 MHz
— Two 4 × 128-bit page buffers with programmable prefetch control
– One set of page buffers can be allocated for code-only, fixed partitions of code and data, all
available for any access
– One set of page buffers allocated to Display Controller Unit and the eDMA
— 64-bit ECC with single-bit correction, double-bit detection for data integrity
— 64 KB data flash memory — separate 4  16 KB flash block for EEPROM emulation with
prefetch buffer and 128-bit data access port
• Small block flash memory arrangement to support features such as boot block, operating system
block
• Hardware managed flash memory writes, erase and verify sequence
• Censorship protection scheme to prevent flash memory content visibility
• Separate dedicated 64 KB data flash memory for EEPROM emulation
— Four erase sectors each containing 16 KB of memory
— Offers Read-While-Write functionality from main program space
— Same data retention and program erase specification as main program flash memory array
2.4.9 Static random-access memory (SRAM)
The PXD10 microcontrollers have up to 48 KB general-purpose on-chip SRAM with the following
features:
• Typical SRAM access time: 0 wait-state for reads and 32-bit writes; 1 wait-state for 8- and 16-bit
writes if back to back with a read to same memory block
• 32-bit ECC with single-bit correction, double bit detection for data integrity
• Supports byte (8-bit), half word (16-bit), and word (32-bit) writes for optimal use of memory
• User transparent ECC encoding and decoding for byte, half word, and word accesses
• Separate internal power domain applied to full SRAM block, 8 KB SRAM block during
STANDBY modes to retain contents during low power mode.
2.4.10 On-chip graphics SRAM
The PXD10 microcontroller has 160 KB on-chip graphics SRAM with the following features:
• Usable as general purpose SRAM
• Typical SRAM access time: 0 wait-state for reads and 32-bit writes
