From 630ec84aef7228fc1dbfb38dec78541403a786cd Mon Sep 17 00:00:00 2001 From: Bartlomiej Sieka Date: Sun, 27 May 2007 17:03:37 +0200 Subject: Motion-PRO: Update EEPROM's page write bits and write delay. Change EEPROM configuration according to the datasheet: "The 24C01A and 24C02A have a page write capability of two bytes", and "This device offers fast (1ms) byte write". Add 3ms of extra delay.
