1. The serial pin control 0 bit enables bidirectional configurations.
2. Slave output is enabled if DDRS4 = 1, SS = 0 and MSTR = 0. (#1, #3)
3. Master output is enabled if DDRS5 = 1 and MSTR = 1. (#2, #4)
4. SCK output is enabled if DDRS6 = 1 and MSTR = 1. (#2, #4)
5. SS output is enabled if DDRS7 = 1, SSOE = 1 and MSTR = 1. (#2, #4)
This bit decides serial pin configurations with MSTR control bit.

Pin Mode
Bidirectional
For More Information On This Product,
0 = No internal pull-ups on port S
1 = All port S input pins have an active pull-up device. If a pin is
0 = Port S output drivers operate normally
1 = All port S output pins have reduced drive capability for lower
0 = Serial interface clock operates normally
1 = Halt serial interface clock generation in WAIT mode
Normal
