Mode Register 3 (MR3 with SR=27H)
Mode Register 3 is organized as a 4-bit binary register (MR3.3 to MR3.0) . The bit descriptions are as following: (Initial
value=0000B)
0
1
2
3
MR3
FsENB
V
LCD
P1
P0
V
LCD
= 0 Use internal LCD supplying voltage generated by pump circuit.
= 1 Use external LCD supplying voltage.
FsENB = 0 Enable 32768 Hz crystal
=1 Disable 32768 Hz crystal
P1 = PWM volumn control bit 1
P0 = PWM volumn control bit 0
Note that any one pin of RC port in low state will force the bit MR3.2 low. It means once any one pin of RC port in low
state, the setting action for this bit is invalid.
Interrupts
The W533X2 provides five internal interrupt sources (Divider, TM0, SPEECH, MELODY and TM1) and two external
interrupt source (port RC and port RD). Vector addresses for each of the interrupts are located in the range of program
memory (ROM) addresses 004H to 020H. The flags IEF, PEF, and EVF are used to control the interrupts. When EVF is
set to "1" by hardware and the corresponding bits of IEF and PEF have been set by software, an interrupt is generated.
When an interrupt occurs, all of the interrupts are inhibited until the
EN INT
or MOV IEF,#I instruction is invoked. The
