Reset Control
The XC886/888 has five types of reset: power-on reset, hardware reset, watchdog timer
reset, power-down wake-up reset, and brownout reset.
When the XC886/888 is first powered up, the status of certain pins (see
Table 23
) must
be defined to ensure proper start operation of the device. At the end of a reset sequence,
the sampled values are latched to select the desired boot option, which cannot be
modified until the next power-on reset or hardware reset. This guarantees stable
conditions during the normal operation of the device.
In order to power up the system properly, the external reset pin RESET must be asserted
until V
DDC
reaches 0.9*V
DDC
. The delay of external reset can be realized by an external
capacitor at RESET pin. This capacitor value must be selected so that V
RESET
reaches
0.4 V, but not before V
DDC
reaches 0.9* V
DDC.
A typical application example is shown in
Figure 23
. For a voltage regulator with IDD
max
= 100 mA, the V
DDP
capacitor value is 10
μ
F. V
DDC
capacitor value is 220 nF. The
capacitor connected to RESET pin is 100 nF.
Typically, the time taken for V
DDC
to reach 0.9*V
DDC
is less than 50
μ
s once V
DDP
reaches 2.3V. Hence, based on the condition that 10% to 90% V
DDP
(slew rate) is less
than 500
μ
s, the RESET pin should be held low for 500
μ
s typically. See
Figure 24
