40.2.43 Pin Select Register 4 (PSEL4)
PSEL4 is a 16-bit readable/writable register that selects the functions of the Port I (PTI) and Port
O (PTO) pins multiplexed with “other function”, and also selects the function of the
IOIS16/TCLK pin and the REF125CK/HAC_BITCLK pin.
When using the pins with “other function” assigned, set PSEL4 and then set the corresponding
port control register to select “other function”.

Description
Selects the function of the IOIS16/TCLK pin.
0: IOIS16 function is selected
1: TCLK function is selected
When the IOIS16 function is selected, this bit should be
set to the initial value.
Do not select the IOIS16 function after the TCLK function
is selected.
Selects the function of the REF125CK/HAC_BITCLK pin.
0: REF125CK function is selected
1: HAC_BITCLK function is selected
Selects the pin for DREQ1
0: Input from PTL5 is used as DREQ1
1: Input from PTO5 is used as DREQ1
Reserved
This bit is always read as 0, and the write value should
always be 0.
