13.2. Reading the Flash Memory

Flash reads occur much faster than Flash write or erase operations and are completed within the minimum read

strobe time specified by the parallel host interface. Flash is read using the FLASHADDRH:FLASHADDRL,

FLASHDATA, and FLASHAUTORD registers. The FLASHAUTORD register provides an efficient method of

accessing sequential data in Flash by automatically incrementing the Flash address pointer after each read.

13.2.1. Flash Read Procedure

Step 1: Set FLASHADDRH:FLASHADDRL to the address of the byte to be read.

Step 2: Read the value of the byte from FLASHDATA.

13.2.2. Multiple Byte Flash Read Procedure

Step 1: Set FLASHADDRH:FLASHADDRL to the address of the first byte to be read.

Step 2: For each byte, read the value from FLASHAUTORD.
