TWI SHORTS register.

[KateChen]

Hello,

About TWI in "nRF51_Reference_manual_v1.1.pdf",there is a register called "SHORTS". I have a few question about this register:

1. Can I use SHORTS register to replace PPI function at "twi_hw_master.c".
2. Is there any thing I should do before changing SHORTS register from BB_SUSPEND enable to BB_STOP enable .

Thank you for your attention! Kate

Unfortunately, on the current revision of the chip, these shortcuts are not functional. This is described in the PAN, item 36 in version 1.6.

However, for completeness, if these shortcuts where functional, they could have replaced the PPI usage.
