Important Note
1.
Please note the ICE is a superset of HE80000 series IC. Each member of the family only has parts of
all resources. Do not use any hardware resource that your target chip doesn’t have, for example,
RAM and register. KBIDS and compiler can’t prevent user from using some hardware resources that
don’t exist in your target chip.
To access “Data ROM”, users must update TPP first, TPH, and then TPL. Only follow this order, the
pre-charge circuit of ROM will work correctly. The 5μs waiting is also necessary before LDV
instruction is executed since Data ROM is a low speed ROM. User can’t emulate this accessing
process in ICE, so 5μs delay should be added by firmware.
LCD driving circuit must be turned off before the system goes into sleep mode.
Please bond the TSTP_P, RSTP_N and PRTD [7:0] with test points on PCB (can be soldered and
probed) as you can, then some testing can be performed on PCB when it’s necessary. The TSTP_P is
suggested to connect to ground by a 0 ohm resistor.
The LVP must be lower than 8.5 volts; otherwise permanent damages to the IC might be incurred.
Please refer to the application note “AN025E” for the detailed LCD power system adjustment.
