3.3 Device Signals
The following device signals should be brought out (i.e., made accessible) so
that the FET, GANG430, and PRGS430 tools can be utilized:
RST/NMI
❏
❏❏
❏ TMS
❏
❏❏
❏ TCK

❏❏
❏ TDI

❏ TEST†
Notes: Design considerations to support the FET, GANG430, and
PRGS430
1) Connections to XIN and XOUT are not required, and should not be
made.
2) PRGS430 software Version 1.10 or greater must be used.
The BSL tool requires the following device signals:
RST/NMI

† If present on device.
‡ ‘1xx devices use pins P1.1 and P2.2 for the BSL. ‘4xx devices use pins P1.0 and P1.1 for the
BSL.
