• Description: Flash Series 8-bit Microcontroller
• Manufacturer: ELAN Microelectronics Corp

Product Specification (V1.0) 05.05.2010
(This specification is subject to change without further notice)
Bit 1 (/PH61): Control bit used to enable pull-high on P61 pin
Bit 0 (/PH60): Control bit used to enable pull-high on P60 pin
The IOCD Register is both readable and writable.
6.2.12 IOCE (Interrupt Mask Register 2)
Bit 7 (CMP2IE): CMP2IF interrupt enable bit.
Bit 6:
Bit 5 (TC3IE): Interrupt enable bit
Bit 4 (TC2IE): Interrupt enable bit
Bit 3 (TC1IE): Interrupt enable bit
Bit 2 (UERRIE): UART receive error interrupt enable bit
Bit 1 (URIE): UART receive mode Interrupt enable bit
Bit 0 (UTIE): UART transmit mode interrupt enable bit.

0: Disable TC2IF interrupt
1: Enable TC2IF interrupt
0: Disable TC1IF interrupt
1: Enable TC1IF interrupt
0: Disable UERRIF interrupt
1: Enable UERRIF interrupt
0: Disable RBFF interrupt
1: Enable RBFF interrupt
0: Disable TBEF interrupt
1: Enable TBEF interrupt
For F641/541N, Bit 7 ~ Bit 6 are unused. Set to “1” all the time.
0: Disable CMP2IF interrupt
1: Enable CMP2IF interrupt
When the Comparator 2 output status change is used to enter an
interrupt vector or enter the next instruction, the CMP2IE bit must be
set to “Enable“.
Not used, set to “0” all the time.
0: Disable TC3IF interrupt
1: Enable TC3IF interrupt
