Table 80 Sleep Mode ‘Always-On’ Control Registers

The ‘Always-On’ digital input / output pins are listed in Table 81. All other digital input pins will have no

effect in Sleep mode. The IRQ

¯¯¯ output is normally de-asserted in Sleep mode.

Note that, in Sleep mode, the IRQ

¯¯¯ output can only be asserted in response to the JD1 or GP5 control

signals (these described in the following section). If the IRQ

¯¯¯ output is asserted in Sleep mode, it can

only be de-asserted after a Wake-Up transition.

Table 81 Sleep Mode ‘Always-On’ Digital Input Pins

A Wake-Up transition is triggered using the JD1 or GP5 control signals (defined below).

It is assumed that DCVDD is supplied by LDO1. The AVDD, DBVDD1 and LDOVDD supplies must be

present throughout the Sleep mode duration. See “Charge Pumps, Regulators and Voltage

Reference” for specific control requirements where DCVDD is not powered from LDO1.

Note that a logic ‘1’ applied to the LDOENA pin will also cause a Wake-Up transition. In this event,

however, the configurable Wake-Up events (described below) are not applicable.
