Port E pin assignment 3
This bit configures the port E3 pin for its alternate function
(SYNCA) or digital I/O.
1 Port E3 pin configured for alternate function (SYNCA)
0 Port E3 pin configured for digital I/O
NOTE: The SIZ1 primary function on the port E3 pin is enabled by
the SZEN bit in the CCR register. Please refer to the
“Chip Configuration Module (CCM)
configuration and the SZEN bit.
Port E pin assignment 2
This bit configures the port E2 pin for its alternate function
(SYNCB) or digital I/O.
1 Port E2 pin configured for alternate function (SYNCB)
0 Port E2 pin configured for digital I/O
NOTE: The SIZ0 primary function on the port E2 pin is enabled by
the SZEN bit in the CCR register. Please refer to the
“Chip Configuration Module
configuration and the SZEN bit.
Port E pin assignment 1.
This two-bit field in PEPAR[3:2] configures the port E1 pin for its

10 Port E1 pin configured for alternate function (SYNCA)
11 Port E1 pin configured for primary function (TS)
Port E pin assignment 0.
This two-bit field in PEPAR[1:0] configures the port E0 pin for its
primary function (TIP), alternate function (SYNCB), or digital I/O.
0x Port E0 pin configured for digital I/O
10 Port E0 pin configured for alternate function (SYNCB)
11 Port E0 pin configured for primary function (TIP)
