HARDWARE DESIGN CONSIDERATIONS
1. Initial Value Setting Pins
but as input pins whose input status determine internal settings during the time that the RESETDRV pin is held at
high level as shown in the diagram below.
(on the order of 10k½ for ordinary circuits).
1.1 SPKROUT# and RI_OUT# Pins
table below :
• RF5C296
• RF5C396
RF5C296/RF5C396L/RB5C396/RF5C396
For the RF5C296 and the RF5C396, the SPKROUT#, RI_OUT#, and INTR# pins function as output pins normally
Internal settings can be made by pulling up or down these pins to such a degree as not to affect normal operation
The SPKROUT# and RI_OUT# pins determine an index range for access to the internal registers as shown in the
