9 / 135 page  Preliminary N79E352/N79E352R Data Sheet Publication Release Date: Jul, 29, 2009 - 9 - Revision A06 5. PIN DESCRIPTIONS SYMBOL Alternate Function 1 Alternate function 2 Type DESCRIPTIONS EA I EXTERNAL ACCESS ENABLE: This pin forces the processor to execute out of external ROM. It should be kept high to access internal ROM. The ROM address and data will not be present on the bus if EA pin is high and the program counter is within internal ROM area. Otherwise they will be present on the bus. PSEN O PROGRAM STORE ENABLE: PSEN enables the external ROM data onto the Port 0 address/data bus during fetch and MOVC operations. When internal ROM access is performed, no PSEN strobe signal outputs from this pin. ALE O ADDRESS LATCH ENABLE: ALE is used to enable the address latch that separates the address from the data on Port 0. XTAL1 P5.1 I/O CRYSTAL1: This is the crystal oscillator input. This pin may be driven by an external clock or configurable i/o pin, P5.1. XTAL2 P5.0 I/O CRYSTAL2: This is the crystal oscillator output. It is the inversion of XTAL1. Also a configurable i/o pin, P5.0. VDD P POWER SUPPLY: Supply voltage for operation. VSS P GROUND: Ground potential. RST RESET: A high on this pin for two machine cycles while the oscillator is running resets the device. P0.0 KB0 AD0 I/O PORT0: Support 4 mode output and 2 mode input. Multifunction pins for AD0-7and KB0-7. P0.1 KB1 AD1 I/O P0.2 KB2 AD2 I/O P0.3 KB3 AD3 I/O P0.4 KB4 AD4 I/O P0.5 KB5 AD5 I/O P0.6 KB6 AD6 I/O P0.7 KB7 AD7 I/O P1.0 T2 I/O PORT1: Support 4 mode output and 2 mode input. Multifunction pins for SDA & SCL (I2C), T2, T2EX and PWM0-1. P1.1 T2EX I/O P1.2 SDA I/O P1.3 SCL I/O P1.4 PWM0 I/O P1.5 PWM1 I/O P1.6 ICPDAT I/O P1.7 ICPCLK I/O |
