MISCELLANEOUS REGISTERS (Cont’d)
10.3 MISCELLANEOUS REGISTER DESCRIPTION
MISCELLANEOUS REGISTER 1 (MISCR1)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:6 = IS1[1:0] ei1 sensitivity
The interrupt sensitivity, defined using the IS1[1:0]
bits, is applied to the ei1 external interrupts. These
two bits can be written only when the I[1:0] bits in
the CC register are set to 1 (interrupt masked).
ei1: Port B (C optional)
Bit 5 = MCO Main clock out selection
This bit enables the MCO alternate function on the
PC2 I/O port. It is set and cleared by software.
0: MCO alternate function disabled (I/O pin free for
1: MCO alternate function enabled (f
Bits 4:3 = IS0[1:0] ei0 sensitivity
The interrupt sensitivity, defined using the IS0[1:0]
bits, is applied to the ei0 external interrupts. These
two bits can be written only when the I[1:0] bits in-
the CC register are set to 1 (interrupt masked).
ei0: Port A (C optional)

Bits 2:1 = CP[1:0] CPU clock prescaler
These bits select the CPU clock prescaler which is
applied in the various slow modes. Their action is
conditioned by the setting of the SMS bit. These
two bits are set and cleared by software
Bit 0 = SMS Slow mode select
This bit is set and cleared by software.
0: Normal mode. f
1: Slow mode. f
