Section 15 Pin Function Controller (PFC)
Bit 8—PA4 Mode (PA4MD): PA4MD selects the function of the PA4/WRL (WR) pin.
Bit 8: PA4MD
0
1
Function
Input/output (PA4)
Lower write output (WRL) or write output (WR)
(Initial value)
Bits 7 and 6—PA3 Mode (PA3MD1 and PA3MD0): PA3MD1 and PA3MD0 select the function
of the PA3/CS7/WAIT pin. This pin has a pull-up MOS that is used when it functions as a WAIT
pin to allow selection of pull-up or no pull-up (for the WAIT pin) using the wait state control
register of the bus state controller (BSC). There is no pull-up when it functions as PA3 or CS7.
