4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
Preliminary
10.15.2002 (V1.3)
P12 and P13 are the 8-bit binary counter registers of the HTC. P12 is lower nibble register and P13 is higher
nibble register.

The HTC can be set initial value and send counter value to counter registers (P13 and P12), P20 and P18
are the command ports for HTC, user can choose different operation mode and different internal clockrate
by setting the port. The timer/counter increase one at the rising edge of internal pulse. The HTC can
generate an overflow interrupt (HTCI) when it overflows. The HTCI can't be generated when the HTC
is in the melody mode or disabled.
CONTROL OF HIGH SPEED COUNTER
The high speed counter is controlled by the command registers (P20, P18) :
