The value of 8-bit binary up counter can be presetted by P10 and P11. The value of registers can loaded into
the HTC when the counter starts counting or occurs overflow. If user write value to the registers before the
next overflow occurs, the preset value can be changed.
The preset value will be changed when users output the different data to P10 and P11.
The count value of HTC can be read from P10 and P11. The value is unstable when user read the value during
counting. Thus, user must disable the counter before reading the value.
The P4.0/SOUND and SOUND pins will output the squre wave in the melody mode. When the CPU is not
in the melody mode, the P4.0/SOUND is high and SOUND is low.
The P4.1/RGH pin will be the input pin in the pulse width measurement mode. User must output high to P4.1/
TRGH and then it can be the HTC external input pin. When the HTC is disabled, the P4.1 pin is a normal I/
O pin.
INTERRUPT FUNCTION
There are 6 interrupt sources, 2 external interrupt sources, 4 internal interrupt sources . Multiple
interrupts are admitted according the priority .
