J. Important Note

1. For accessing any address large than 64KB, users must update TPP first, TPH then TPL. Only by this

order, the pre-charge circuit of ROM will work correctly. 5us waiting is necessary before LDV

instruction is executed since Data ROM is a low speed ROM. Users can not emulate this accessing

process in ICE. So 5us delay should be added by firmware.

2. LCD driving circuit must be turn off before IC goes into sleep mode.

3. Please bonds the TSTP_P, RSTP_N and PRTD[7:0] with test point on PCB (can be soldered and

probed) as you can, then KB can do some IC testing job on PCB. Please connect TSTP_P pin with

(Testing point with through hole).

4. LV5 must small than 9.0 Volt. Otherwise IC may breakdown.
