are read back again, but as previously discussed, a nop instruction is included to be able to read
back the value recently assigned to some of the pins.
Note:
1. For the assembly program, two temporary registers are used to minimize the time from pull-
ups are set on pins 0, 1 and 4, until the direction bits are correctly set, defining bit 2 and 3 as
low and redefining bits 0 and 1 as strong high drivers.

Digital Input Enable and Sleep Modes
As shown in Figure 11-2 on page 64, the digital input signal can be clamped to ground at the
input of the schmitt-trigger. The signal denoted SLEEP in the figure, is set by the MCU Sleep
Controller in Power-down mode, Power-save mode, and Standby mode to avoid high power
consumption if some input signals are left floating, or have an analog signal level close to V
CC/2.
SLEEP is overridden for port pins enabled as external interrupt pins. If the external interrupt
request is not enabled, SLEEP is active also for these pins. SLEEP is also overridden by various
other alternate functions as described in “Alternate Port Functions” on page 69.
If a logic high level (“one”) is present on an asynchronous external interrupt pin configured as
“Interrupt on Rising Edge, Falling Edge, or Any Logic Change on Pin” while the external interrupt
is not enabled, the corresponding External Interrupt Flag will be set when resuming from the
