2-4. Change in the Timer RG Function
Do NOT set the count source select bits (TCK2 to TCK0) in the timer RG control register (TRGCR) to 001b (f2 selected as
the count source of timer RG) [refer to Figure 2-5].
2-5. Changes in the LCD Port Function
2-5-1. LCD Port Select Register 0 (LSE0)
This information applies to the R8C/L35A Group, R8C/L36A Group, R8C/L35B Group, and R8C/L36B Group.
Do NOT set bits LSE06 and LSE07 to 1 (SEG6 and SEG7 port functions selected). P0_6/SEG6 and P0_7/SEG7 cannot be
used as segment pins SEG6 and SEG7. P0_6/SEG6 and P0_7/SEG7 can be used as I/O ports P0_6 and P0_7.
2-5-2. LCD Port Select Register 2 (LSE2)
This information applies to the R8C/L38A Group and R8C/L38B Group.
Do NOT set the LSE16 bit to 1 (SEG16 port function selected). P2_0/SEG16/KI0 cannot be used as segment pin SEG16.
P2_0/SEG16/KI0 can be used as I/O port P0_2 and KI0.
2-6. Voltage Monitor 0 Reset and Power-On Reset
The voltage monitor 0 reset and power-on reset cannot be used. Use a hardware reset to reset the MCU. In the documents
listed in section 1-2, descriptions of the voltage monitor 0 reset and power-on reset are invalid.
2-7. Removed the Voltage Monitor 1 / Comparator A1 Interrupt and Voltage Monitor 2 / Comparator A2 Interrupt Functions
Voltage monitor 1 / comparator A1 and voltage monitor 2 / comparator A2 cannot be used. In the documents listed in section
1-2, description of the voltage monitor 0 reset or power-on reset are invalid.
2-8. Note on Reducing Power Current
Write 00h to the POMCR0 register (address 0020h) by a program. Current consumption may increase until 00h is written to
the POMCR0 register.
Sample code: MOV.B #00H, 0020H
3. Other Note
Note regarding pins P12_1 and P12_0.
P12_1 and P12_0 are shared with XIN and XOUT. When XIN is used as a clock, these ports cannot be used as I/O ports.
4. Slated Changes
Contact the Renesas Technology sales department for schedule and products with high-speed on-chip oscillator.
