Nexus 2+ pins
In the 208 MAPBGA package, eight additional debug pins are available (see Table 6).
1 Alternate functions are chosen by setting the values of the PCR.PA bitfields inside the SIUL module.
PCR.PA = 00
AF0; PCR.PA = 01 AF1; PCR.PA = 10 AF2; PCR.PA = 11 AF2. This is intended to
select the output functions; to use one of the input functions, the PCR.IBE bit must be written to ‘1’, regardless of
the values selected in the PCR.PA bitfields. For this reason, the value corresponding to an input only function is
reported as “—”.
2 Multiple inputs are routed to all respective modules internally. The input of some modules must be configured by
setting the values of the PSMIO.PADSELx bitfields inside the SIUL module.
3 The RESET configuration applies during and after reset.
4 208 MAPBGA available only as development package for Nexus2+
5 All WKPU pins also support external interrupt capability. See the WKPU chapter for further details.
6 NMI has higher priority than alternate function. When NMI is selected, the PCR.AF field is ignored.
7 “Not applicable” because these functions are available only while the device is booting. Refer to the BAM
information for details.
8 Value of PCR.IBE bit must be 0
9 This wakeup input cannot be used to exit STANDBY mode.
10 Out of reset all the functional pins except PC[0:1] and PH[9:10] are available to the user as GPIO.
PC[0:1] are available as JTAG pins (TDI and TDO respectively).
PH[9:10] are available as JTAG pins (TCK and TMS respectively).
It is up to the user to configure these pins as GPIO when needed.
11 PC[1] is a fast/medium pad but is in medium configuration by default. This pad is in Alternate Function 2 mode after
reset which has TDO functionality. The reset value of PCR.OBE is ‘1’, but this setting has no impact as long as this
pad stays in AF2 mode. After configuring this pad as GPIO (PCR.PA = 0), output buffer is enabled as reset value
of PCR.OBE = 1.
