CHAPTER 29 SYSTEM CONFIGURATION CONTROLLER
29.2 Register
[bit2] PPGSEL: 8/16-bit PPG output pins select bit
This bit selects the 8/16-bit PPG output pins.
[bit1] RSTOE: Reset output enable/disable bit
This bit enables or disables the reset output function of the PF2/RST pin with the reset input function
enabled. When the reset input function is disabled (SYSC:RSTEN = 0), the reset output function is disabled
regardless of the setting of this bit.
See the PF2 function select bit (SYSC:RSTEN) for details of selecting the reset input function.
[bit0] RSTEN: PF2 function select bit
This bit enables or disables the reset input function of the PF2/RST pin. The reset input function is always
enabled on MB95F632H/F633H/F634H/F636H regardless of the setting of this bit.
Writing "0" to this bit disables the reset input function of the PF2/RST
pin and enables the general-purpose
I/O port function.
Writing "1" to this bit enables the reset input function of the PF2/RST
pin and disables the general-purpose
I/O port function.
Set bit2 in the PDRF register to "1" before modifying this bit.
Note:
To keep the reset input/output function after the reset, SYSC:RSTEN and SYSC:RSTOE
are initialized to "1" after the power is switched on. They are not initialized by any other
type of reset.
When the reset input/output functions have to be used in a system, it is strongly
recommended that SYSC:RSTEN be initialized to "1" in the initialize program routine after
a reset for stable operation. With the reset input/output functions having been enabled, all
types of reset, including the watchdog reset, can be used.
bit2 Details
Writing "0" Selects P10, P11, and P13 to P16 as 8/16-bit PPG output pins.
Writing "1" Selects P62 to P67 as 8/16-bit PPG output pins.
Relation between PPG channels and pins
PPG channel PPGSEL = 0 PPGSEL = 1
ch. 0 P13, P14 P62, P63
ch. 1 P10, P11 P64, P65
ch. 2 P15, P16 P66, P67
bit1 Details
Writing "0" Disables the reset output function of the PF2/RST pin.
Writing "1" Enables the reset output function of the PF2/RST pin.
bit0 Details
Writing "0" Selects the general-purpose I/O port function of the PF2/RST pin.
Writing "1" Selects the reset output function of the PF2/RST pin.
