4.5 MISCELLANEOUS REGISTER
The Miscellaneous register allows to select the
SLOW operating mode, the polarity of external in-
terrupt requests and to output the internal clock.
Register Address: 0020h
—
Read /Write
Reset Value: 0000 0000 (00h)
Bit 7:6 = PEI[3:2]
External Interrupt EI1 Polarity
Option.
These bits are set and cleared by software. They
determine which event on EI1 causes the exter-
nal interrupt according to Table 8.
Table 8. EI1 External Interrupt Polarity Options
Note: Any modification of one of these two bits re-
sets the interrupt request related to this interrupt
vector.
Bit 5 = MCO
Main Clock Out
This bit is set and cleared by software. When set, it
enables the output of the Internal Clock on the
PC2 I/O port.
0 - PC2 is a general purpose I/O port.
1 - MCO alternate function (fCPU is output on PC2
pin).
Bit 4:3 = PEI[1:0]
External Interrupt EI0 Polarity
Option.
These bits are set and cleared by software. They
determine which event on EI0 causes the exter-
nal interrupt according to Table 9.
Table 9. EI0 External Interrupt Polarity Options
Note: Any modification of one of these two bits re-
sets the interrupt request related to this interrupt
vector.
Bit 1:2 = Unused, always read at 0.
Warning: Software must write 1 to these bits for
compatibility with future products.
Bit 0 = SMS
Slow Mode Select
This bit is set and cleared by software.
0- Normal mode - fCPU = Oscillator frequency / 2
(Reset state)
1- Slow mode - fCPU = Oscillator frequency /32
