4.3.21 SNOOZE status output control register 2 (PSNZCNT2)
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.

PSNZCNT2 0 0 SNZACT5 OUTEN5 0 0 SNZACT4 OUTEN4
SNZACT5 SNZOUT5 active level
0 When PIOR65 = 0: Active level of SNOOZE status output to P71 is "H".
When PIOR65 = 1: Active level of SNOOZE status output to P156 is "H" (only in 100-pin products).

When PIOR65 = 1: Active level of SNOOZE status output to P156 is "L" (only in 100-pin products).
OUTEN5 SNZOUT5 enable/disable
0 When PIOR65 = 0: SNOOZE status output to P71 is disabled.
When PIOR65 = 1: SNOOZE status output to P156 is disabled (only in 100-pin products).
1 When PIOR65 = 0: SNOOZE status output to P71 is enabled.
When PIOR65 = 1: SNOOZE status output to P156 is enabled (only in 100-pin products).
SNZACT4 SNZOUT4 active level
0 When PIOR64 = 0: Active level of SNOOZE status output to P70 is "H".
When PIOR64 = 1: Active level of SNOOZE status output to P157 is "H" (only in 100-pin products).
1 When PIOR64 = 0: Active level of SNOOZE status output to P70 is "L".
When PIOR64 = 1: Active level of SNOOZE status output to P157 is "L" (only in 100-pin products).
OUTEN4 SNZOUT4 enable/disable
0 When PIOR64 = 0: SNOOZE status output to P70 is disabled.
When PIOR64 = 1: SNOOZE status output to P157 is disabled (only in 100-pin products).
1 When PIOR64 = 0: SNOOZE status output to P70 is enabled.
When PIOR64 = 1: SNOOZE status output to P157 is enabled (only in 100-pin products).
Caution The 20-pin, 30-pin, and 32-pin products do not have the PSNZCNT2 register.
