5.12.3 Mode Register 0 (MR0)
Mode Register 0 is organized as a 4-bit binary register (MR0.0 to MR0.3). MR0 can be used to control
the operation of Timer 0. The bit descriptions are as follows:
0
1
2
3
Note: W means write only.
Bit 0 = 0 The fundamental frequency of Timer 0 is F
OSC
/4.
= 1 The fundamental frequency of Timer 0 is F
OSC
/1024.
Bit 1 & Bit 2 are reserved
Bit 3 = 0 Timer 0 stops down-counting.
= 1 Timer 0 starts down-counting.

5.12.4 Mode Register 1 (MR1)
Mode Register 1 is organized as a 4-bit binary register (MR1.0 to MR1.3). MR1 can be used to control
the operation of Timer 1. The bit descriptions are as follows:
Note: W means write only.

Bit 0 = 0 The internal fundamental frequency of Timer 1 is F
OSC
.
= 1 The internal fundamental frequency of Timer 1 is F
OSC
/64.
Bit 1 = 0 The fundamental frequency source of Timer1 is the internal clock.
= 0 The fundamental frequency source of Timer1 is the sub-oscillator frequency Fs
(32.768 KHz).
Bit 2 = 0 The specified waveform of the MFP generator is delivered at the MFP output pin.
= 1 The specified frequency of Timer 1 is delivered at the MFP output pin.
Bit 3 = 0 Timer 1 stops down-counting.
= 1 Timer 1 starts down-counting.
5.13 Interrupts
The W742E/C813 provides four internal interrupt sources (Divider 0, Divider 1, Timer 0, Timer 1) and
seven external interrupt source (port P1.2 (INT0 ), RC.0-3, Serial port, P1.3 (INT1)). Vector addresses
for each of the interrupts are located in the range of program memory (ROM) addresses 004H to
023H. 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, the corresponding bit of EVF will be clear, and all of the
interrupts will be inhibited until the EN INT or MOV IEF,#I instruction is invoked
.
Normally, the
EN INT instruction will be asserted before the RTN instruction
. The interrupts can also be disabled
