MISCELLANEOUS REGISTER 3 (MISCR3)
Reset Value: 0000 0000 (00h)
Read/Write
This register is used to configure the edge and the
level sensitivity of the Port A and Port C external
interrupt. This means that all bits of a port must
have the same sensitivity.
If a write access modifies bits 7:4, it clears the
pending interrupts.
CTRL0_C, CTRL1_C : Sensitivity on port C
CTRL0_A, CTRL1_A : Sensitivity on port A
MISCELLANEOUS REGISTER 4 (MISCR4)
Reser Value : 0000 0000 (00h).
Read/Write
Bit 7 = Reserved.
Bit 6 =
PLL_ON
PLL Activation
0: PLL disabled
1: PLL enabled
Note:
The PLL must be disabled before a HALT
instruction.
Bit 5 =
CLK_SEL
Clock Selection
This bit is set and cleared by software.
0: CPU frequency = 4MHz
1: CPU frequency = 8MHz
Bits 4:1 = Reserved.
Bit 0 =
LOCK
PLL status bit
0: PLL not locked. f
CPU
= f
OSC
external clock fre-
quency.
1: PLL locked. f
CPU
= 4 or 8 MHz depending on
CLKSEL bit.
