The CPU includes non-volatile data storage: a Disk on Module (DOM) with an
embedded flash chip.
7.4.2.1. DISK-ON-MODULE (DOM)
The DOM is a 44-pin IDE flash chip with storage capacity to 129 MB. It is used
to store the operating system, the Teledyne API firmware, and most of the
operational data generated by the analyzer’s internal data acquisition system
(DAS - see Section 4.7).
7.4.2.2. FLASH CHIP
This non-volatile, embedded flash chip includes 2MB of storage for calibration
