1.2
PWM
The nRF9E5 has one programmable PWM (Pulse-Width Modulation) output, which is
the alternate function of P0.7. The resolution of the PWM is software programmable to
6, 7 or 8 bits. The frequency of the PWM signal is programmable via a 6 bit prescaler
from the XTAL oscillator. The duty cycle is programmable between 0% and 100% via
one 8-bit register.
1.3
SPI
nRF9E5 features a simple single buffered SPI (Serial Programmable Interface) master.
The 3 data lines of the SPI bus (MISO, SCK and MOSI) are multiplexed (by writing to
register SPI_CTRL) between the GPIO pins (lower 3 bits of P1) and the RF transceiver
and AD subsystems. The SPI hardware does not generate any chip select signal. The
programmer will typically use GPIO bits (from port P0) to act as chip selects for one or
more external SPI devices. The EECSN pin is a general purpose IO dedicated as chip
select for the boot EEPROM. When the SPI interfaces the RF transceiver, the chip
selects are available in an internal GPIO port, P2.
1.4
Port Logic
The device has 8 general-purpose bi-directional pins (the P0 port). Additionally the 4
SPI data pins may be used as general purpose IO (the P1). Most of the GPIO pins can
be used for multiple purposes under program control. The alternate functions include
two external interrupts, UART RXD and TXD, a SPI master port, three enable/count
signals for the timers and the PWM output and a slow programmable timer. Each pin in
the P0 port can be programmed for high sink or source current.
