EXTPUL
A logic 1 indicates that an external 1.5 k
pull-up resistor is
used on pin D
+
and that SoftConnect is not used. Bus reset
value: unchanged.
13
NOLAZY
A logic 1 disables output on pin CLKOUT of the LazyClock
frequency (24 kHz) during ‘suspend’ state. A logic 0 causes pin
CLKOUT to switch to LazyClock output after approximately 2 ms
delay, following the setting of bit GOSUSP in the Mode Register.
Bus reset value: unchanged.
12
CLKRUN
A logic 1 indicates that the internal clocks are always running,
even during ‘suspend’ state. A logic 0 switches off the internal
oscillator and PLL, when they are not needed. During ‘suspend’
state this bit must be made logic 0 to meet the suspend current
requirements. The clock is stopped after a delay of
approximately 2 ms, following the setting of bit GOSUSP in the
Mode Register. Bus reset value: unchanged.
11 to 8
CKDIV[3:0]
This field specifies the clock division factor N, which controls the
clock frequency on output CLKOUT. The output frequency in
MHz is given by
3 to 48 MHz (N = 0 to 15). with a reset value of 12 MHz (N = 3).
The hardware design guarantees no glitches during frequency
change. Bus reset value: unchanged.
7
DAKOLY
A logic 1 selects DACK-only DMA mode. A logic 0 selects 8237
compatible DMA mode. Bus reset value: unchanged.
6
DRQPOL
Selects DREQ signal polarity (0 = active LOW, 1 = active
HIGH). Bus reset value: unchanged.
5
DAKPOL
Selects DACK signal polarity (0 = active LOW, 1 = active HIGH).
Bus reset value: unchanged.
4
EOTPOL
Selects EOT signal polarity (0 = active LOW, 1 = active HIGH).
Bus reset value: unchanged.
3
WKUPCS
A logic 1 enables remote wake-up via a LOW level on input CS.
Bus reset value: unchanged.
