9.2.3 Port B Data Direction Register (PBDDR)
PBDDR is an 8-bit write-only register that selects input or output for each pin in port B.
Bit
PB DDR
Initial value
Read/Write
Port B is multiplexed with pins TP
must be set to 1. For further information about PBDDR, see section 7.11, Port B.
9.2.4 Port B Data Register (PBDR)
PBDR is an 8-bit readable/writable register that stores TPC output data for groups 2 and 3, when
these TPC output groups are used.
Bit
PB
Initial value
Read/Write
R/(W)
Note: * Bits selected for TPC output by NDERB settings become read-only bits.
For further information about PBDR, see section 7.11, Port B.
