4.3.22 SNOOZE status output control register 3 (PSNZCNT3)
This register is used to output signals indicating that the SNOOZE mode has been entered through external pins.
It can be set by a 1-bit or 8-bit memory manipulation instruction.
Bits 7, 6, 3, and 2 are read-only because no functions are assigned to them. The other bits can be read or written to.
Any reset source clears this register to 00H.
Cautions 1. Set the target port pin to the output mode and the output latch to 0 before using the SNOOZE
status output control register.
2. Stop the output from peripheral functions assigned to output-enabled port pins and make the
register settings at the time of SNZOUT output.
3. Set WUTMMCK0 to 1 at the time of SNZOUT output.

0 When PIOR66 = 0: Active level of SNOOZE status output to P72 is "H".
When PIOR66 = 1: Active level of SNOOZE status output to P155 is "H" (only in 100-pin products).
1 When PIOR66 = 0: Active level of SNOOZE status output to P72 is "L".
When PIOR66 = 1: Active level of SNOOZE status output to P155 is "L" (only in 100-pin products).
OUTEN6 SNZOUT6 enable/disable
0 When PIOR66 = 0: SNOOZE status output to P72 is disabled.
When PIOR66 = 1: SNOOZE status output to P155 is disabled (only in 100-pin products).
1 When PIOR66 = 0: SNOOZE status output to P72 is enabled.
When PIOR66 = 1: SNOOZE status output to P155 is enabled (only in 100-pin products).
Caution The 20-pin, 30-pin, and 32-pin products do not have the PSNZCNT3 register.
