12 / 57 page  EM78P447N OTP ROM 8. R3F (Interrupt Status Register) Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 - - - - EXIF - - TCIF • Bit 3 (EXIF) External interrupt flag. Set by falling edge on /INT pin, flag cleared by software • Bit 0 (TCIF) the TCC overflow interrupt flag. Set as TCC overflows; flag cleared by software. • Bits 1, 2, 4~7 are not used and read are as “0”. • "1" means interrupt request, "0" means non-interrupt. • R3F can be cleared by instruction, but cannot be set by instruction. • IOCF is the interrupt mask register. • Note that reading R3F will obtain the result of the R3F "logic AND" and IOCF. 4.2 Special Purpose Registers 1. A (Accumulator) • Internal data transfer, or instruction operand holding. • It cannot be addressed. 2. CONT (Control Register) 7 6 5 4 3 2 1 0 /PHEN /INT TS TE PAB PSR2 PSR1 PSR0 • Bit 7 (/PHEN) Control bit used to enable the pull-high of P60~P67, P74 and P75 pins 0: Enable internal pull-high. 1: Disable internal pull-high. • CONT register is both readable and writable. • Bit 6 (/INT) Interrupt enable flag 0: masked by DISI or hardware interrupt 1: enabled by ENI/RETI instructions • Bit 5 (TS) TCC signal source 0: internal instruction cycle clock 1: transition on TCC pin • Bit 4 (TE) TCC signal edge 0: increment if the transition from low to high takes place on TCC pin 1: increment if the transition from high to low takes place on TCC pin • Bit 3 (PAB) Prescaler assignment bit. This specification is subject to change without prior notice. 10.21.2004 (V1.0) 12 |
