78K0/Kx2
(6) Port mode register 2 (PM2)
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
When using the ANI0/P20 to ANI7/P27 pins for analog input port, set PM20 to PM27 to 1. The output latches of P20
to P27 at this time may be 0 or 1.
If PM20 to PM27 are set to 0, they cannot be used as analog input port pins.
PM2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
Remark ANI0 to ANI3: 78K0/KB2
ANI0/P20 to ANI7/P27 pins are as shown below depending on the settings of ADPC, ADS, and PM2.

Caution For the 38-pin products of 78K0/KC2, be sure to set bits 6 and 7 of PM2 to “1”, and bits 6 and
Remark The format of port mode register 2 of 78K0/KB2 products is different from the above format. See 5.3
